1 JUPITER 0 0 PV C 100.000 YUICHIRO EZOE REVEALING TRANSPORTATION AND ACCELERATION OF PARTICLES IN JUPITER'S MAGNETOSPHERE We propose observation of Jupiter to investigate long standing issues, i.e., the plasma transportation and the global acceleration of particles in Jupiter's magnetosphere. It is the most luminous planet in X-rays. The X-ray emission is composed of aurorae and disk. The former is due to charge exchange (CX) of several MeV/u ions and bremsstrahlung by keV electrons. The latter is due to scattering of solar X-rays. Suzaku found a sign of diffuse X-ray emission from inner radiation belts, possibly arising from inverse Compton scattering of solar photons by tens MeV electrons. With Resolve, we investigate CX emission lines to reveal the origin and kinematics of the ions and constrain the diffuse X-ray emission with Xtend.
2 C/2021 S3 PanSTARRS 0 0 PV A 100.000 YUICHIRO EZOE DIAGNOSTICS OF CHARGE EXCHANGE EMISSION FROM COMET C/2017 K2 We propose observation of comets to diagnose charge exchange (CX) models and databases and to investigate the chemical abundance of solar wind ions and cometary neutrals. The cometary X-rays are mainly produced by the CX process between highly charged ions in solar winds and neutral atoms or molecules in cometary coma. CX plays an important role in other astronomical objects such as solar system planets, supernova remnants, and clusters of galaxies. Among these objects, cometary X-ray emission represents the best laboratory for investigating the CX process itself. Only Resolve with high energy resolution for the diffuse X-ray emission can clearly measure the CX emission lines from high charge state ions. With Xtend, we will observe the spatial distribution of neutrals in the cometary coma.

We propose here for observations of both the center of the remnant and the SE Fe-rich knot for 75 ks each as a minimal observation goal.

20 NGC 1365 53.40154 -36.14039 PV A 250.000 ERIN KARA STUDYING PHOTOIONISED OUTFLOWS IN A LUMINOUS STAR-FORMING AGN NGC 1365 is a Seyfert 1.8 galaxy with a rich spectrum of narrow emission and absorption lines. It shows the most robust evidence for four Fe XXV/Fe XXVI K-alpha/K-beta absorption lines from a highly ionised outflow. It shows variable obscuration on timescales as short as days, and relativistically broadened iron line. As it is highly variable down to timescales of hours, it is an ideal target for timing analysis with the Xtend+Resolve instruments. It is also a beautiful example of a luminous AGN in a highly star-forming galaxy, providing an opportunity to probe the AGN-starburst connection. With Resolve, we will, for the first time, robustly measure P Cygni profiles from an ionised wind in an AGN to make an independent estimate of the radius, therefore constraining the launching mechanism.

In this source, we explore a binary supermassive black hole by resolving dual Fe-Kalpha lines at 6.4 keV. It is also the best target to study properties of starburst plasmas and their connection to the AGN activity by resolving Fe XXV and Fe XXVI lines from starburst activity. We furthermore aim to determine the detailed profile of an UFO absorption line at 7.8 keV, and constrain its connection to molecular outflows in the host galaxy.

37 SN 1987A 83.86675 -69.26975 PV A 100.000 YUKIKATSU TERADA TIME EVOLUTION OF YOUNG NEI PLASMA IN SN 1987A The nascent core-collapse supernova remnant SN1987A presents a unique opportunity to observe the rapid time evolution of a non-equilibrium ionization (NEI) collisional plasma at early evolutionary timescales. During the XRISM mission life, the NEI plasma emission from the ejecta is expected to become dominant as compared to the emission from the surrounding equatorial ring and HII regions. The minimal goal is to separate and characterize the ejecta emission by the high-resolution spectra. The ideal goal is to measure the time evolution with two observations to directly study the structure and chemical composition of the ejecta to limit progenitor types. Another bonus is to observationally verify the Rankine-Hugoniot relation from ion temperatures by species.

44 VELA X-1 135.52833 -40.55469 PV C 70.000 TIMOTHY KALLMAN PROBING THE WIND-COMPACT OBJECT INTERACTION IN VELA X-1 We propose to observe Vela X-1, the prototypical High Mass X-ray Binary in order to study the spectrum and its variability. The observation is designed to study the variability with the X-ray pulse and the variability with the binary orbit. This will allow constraints on the shape of the pulsar beam, which has previously been done only very crudely. It will allow us to determine the mean density of gas in the wind as it interacts with the pulsar, and to constrain iron peak abundances. We will search for pulsations in the lines, which will provide information about the pulsar beam as seen by many different lines of sight at once. Observations of Vela X-1 are virtually guaranteed to produce spectra which are of high statistical significance and rich in line features. They will provide
45 2S0921-630 140.64446 -63.29481 PV C 80.000 CHRIS DONE THE LAUNCH MECHANISM OF ACCRETION DISC WINDS: THE BEST TESTS FROM THE NEUTRON STAR BINARIES GX13+1 AND 2S0921-630 Accretion disc winds are clearly seen in black hole and neutron star binaries, but their origin is controversial. Are they magnetically driven, connecting them to the jet as well as to the accretion process itself, or are they thermal/radiative, driven by X-ray irradiation of the outer disc? GX13+1 persistently shows a massive wind in absorption, and is the most reliable LMXRB wind source to address the key question of the origin of the wind. A 30ks Resolve observation can directly measure the wind velocity profile along the line of sight, which will distinguish between magnetic and thermal-radiative acceleration. An additional 80ks observation of 2S0921 will instead shows the wind in emission, as its very high inclination angle means the X-ray source is obscured by the disc.
46 M81 148.88825 69.06536 PV C 100.000 JON MILLER A RADIATIVELY INEFFICIENT ACCRETION FLOW IN THE LINER M81* Up to 40% of all galaxies may harbor low-ionization nuclear emission region (LINERs) and low-luminosity AGN (LLAGN). Well-developed theory suggests that the inner flow should be advective and radiatively inefficient, with a standard thin disk truncated far from the black hole. Resolve spectroscopy of M81* offers the best chance to finally reveal the geometry and dynamics of a radiatively inefficient accretion flow (RIAF) onto a black hole. M81* is the brightest LINER /LLAGN in X-rays. Prior Chandra/HETG spectra reveal low-ionization and He-like and H-like Fe K emission lines that are likely redshifted. A 100 ks exposure with Resolve can make unique tests of RIAF models.
47 M82 148.96967 69.67939 PV A 50.000 IKUYUKI MITSUISHI DIRECT VELOCITY MEASUREMENT OF X-RAY EMITTING HOT GAS IN STARBURST-DRIVEN OUTFLOWS IN M82 AND NGC 253 WITH XRISM/RESOLVE Observational facts that metals in the intergalactic medium are found at low and high redshifts suggest that some part of all metals ever created now reside outside galaxies. Galactic-scale starburst-driven outflows are one of the best-studied and most common form of outflow capable of transporting substantial amount of materials inside galaxies into intergalactic space. To verify the scenario, we propose to observe the most prominent nearby galactic-scale starburst phenomena occurred around the nuclear regions of M82 and NGC253. Resolve observations would realize direct measurements of outflow velocity for X-ray emitting hot gas which is a link between galaxies and intergalactic space and the results would yield new insights in the both chemical and dynamical evolution of the Universe.

49 CARINA NORTH 160.96071 -59.64275 PV C 30.000 KENJI HAMAGUCHI ORIGIN AND DYNAMICS OF DIFFUSE X-RAY EMISSION FROM THE CARINA NEBULA The Carina nebula, one of the most massive star-forming regions in our neighborhood, is accompanied by bright diffuse X-ray emission, whose origin is not understood. Previous Suzaku and Chandra observations found substantial spatial variations in the Fe L, and Si and O K emission lines. If they reflect abundance variations, the diffuse plasma is probably a supernova remnant or merged multiple supernova remnants. However, the spectra also show multiple unidentified emission lines, which may suggest complicated plasma conditions. We propose XRISM observations of two regions in the Carina nebula to resolve emission lines in their spectra for the first time. We will also measure the Doppler motions of these emission lines.

The X-ray spectra show strong He-like iron K lines from the hot plasma and iron K fluorescence produced by absorption and reemission of the hard X-ray emission at the primary wind. These emission lines should hold crucial information on the shocked gas at the head-on collision, which would flow with a few hundred to thousand km s-1. The star is also surrounded by a ring-shaped diffuse soft X-ray nebula, whose emission lines may show Doppler broadening or shift if the nebula originates from a supernova imposter event in the 1840s. We aim to resolve these emission line features for the first time with XRISM/Resolve.

For NS-hosting HMXBs, which are of particular interests for the most plausible NS-NS merger progenitors, the standard binary evolution theory meets some serious challenges. One thing that is not considered well in the standard theory is the non-isotropy of the wind mass loss from the high-mass donor. Doppler tomography is an established method in the optical/UV band for the velocity mapping of a binary system, which can be applied in the X-ray band for the first time by using Resolve. Cen X-3 is the target of choice. The wind velocity field can be mapped using photo-ionized X-ray emission lines. Here, we propose a Resolve observation for one entire orbit (2.1 days) to construct a phase-resolved high-resolution X-ray spectra.

Its outflow has been studied extensively for the lower ionization components, but the highest ionized gas has barely been detected despite >Ms exposures with Chandra. A deep 200 ks exposure with XRISM, lasting 4 days, will yield the full velocity-resolved absorption measure distribution, from the lowest to the highest ionization stages. Its variability constrains its distance. Finding ultra-fast outflows or obscuration events, both transient phenomena, is another exciting opportunity.

The largest class flares that affect can only be quantified by studying other stars like the Sun. Investigations of stellar flares in the X-rays provide unique information on the non-thermal aspects of flares, which made steady progress in the last decade. Spectroscopy with an X-ray micro-calorimeter will make a giant leap by providing a new toolbox that has not been realized even in the X-ray observations of the Sun. Here, we propose a MAXI-triggered ToO observation of GT Mus, or other star with a slow development, for the Doppler shifts and off-CIE plasma diagnostics to investigate the non-thermal aspects of stellar flares.

Here we propose to observe NGC 4388, which exhibits the brightest narrow Fe-Ka emission line among Compton-thin Seyfert 2 Galaxies. The bright narrow Fe-Ka line, Compton-thin absorption, and high inclination make it the best target for studying the ``torus'' and inner region. With Resolve, we can for the first time measure the detailed line profile itself, leading to unbiased determination of matter distribution profile around the nucleus.

The hot intracluster medium in the Centaurus cluster has the highest metallicity among the X-ray brightest clusters in the sky. Its central iron abundance is about 1.5 times the solar value, which suggests an effective enrichment by Type Ia supernovae. Thus the Centaurus cluster is an ideal target to study detailed chemical enrichment through XRISM observations.

The spectrum determines the flow of kinetic energy down the turbulent cascade and the amount that dissipates into heat and feeds cosmic ray acceleration and magnetic field amplification. The nearby Coma cluster is the best system for such a measurement, as it does not have a cool core or a powerful AGN, thus all gas motions should be merger-generated and the turbulence should develop in an isotropic, textbook fashion. Our full mosaic of 5 pointings will yield a measurement of the power spectrum normalization and injection scale, a combination that determines the energy flow. Our minimum case is the first detection of turbulence in a merging cluster using the central pointing.

The launch of XRISM will offer a revolutionary new perspective on this fascinating source, giving us the ability to characterize its spectral signatures in unprecedented detail. These features include narrow emission lines from distant reflection, a broadened and skewed Fe Kα line from inner disk reflection, and outflowing winds in absorption that span orders of magnitude in their physical and kinematic properties. Herein, we propose two observing scenarios for MCG6 during the PV phase of the XRISM mission.

However, the mass, energy, ionization history, and distribution of this galactic cytoplasm remain poorly constrained because it has primarily been studied at low spectral resolution (~100 eV) where the principal line complexes are unresolved. Here we propose a XRISM observation of the hot ISM in the nuclear and spiral arm regions of M51, from which we will derive the emission measure distribution as a function of temperature, map chemical abundances, and search for signs of non-equilibrium ionization and charge exchange. M51 is an X-ray bright, but otherwise typical, late-type galaxy and this observation wil

Discovery of a natal supernova remnant makes Circinus X-1 the youngest X-ray binary hosting a neutron star in our Galaxy. Around the periastron passage, different types of X-ray flares, originating from disk or wind accretion, have been found with rich Fe-line structures, P-Cygni, emission, absorption, and edge features.

It is a hard X-ray luminous symbiotic recurrent nova, with an estimated WD mass of >1.15 Msun, above the likely upper limit of WD birth mass. If confirmed, it implies that the WD in T CrB is growing in mass, establishing a subset of symbiotic stars as a viable progenitor channel of Type Ia supernovae. The primary X-ray source is located just above the WD surface, and it is the latter that produces the reflection continuum and the Fe Kalpha and Kbeta fluorescent lines. Measuring the centroids of both will enable us to determine the ionization state of the WD photosphere and the WD mass.

We will characterise the absorbers throughout the orbit (column densities, degree of ionisation and velocity width and shift) and determine their density and location. We will use the changes in the absorbers' properties to model the complex spectral changes throughout the orbit, including during dips, and to trace the variability of the absorber associated with changes in the source luminosity and hardness. We will use this information to make a full map of the accretion disc and identify potential zones of wind launching in LMXBs, shielded regions in the disc or zones that attenuate the central emission such as hot coronae.

This source is the ideal candidate to study dense, never explored before, regions of the Galaxy. We will model the Si, S, Ca and Fe K-edges due to dust absorption. This will allow us to assess the silicate content (through Si and Fe) and its Ca inclusion in the core, as well as the sulphate content (through S and Fe).

This UFO is both of high statistical significance and per- sistent; it has been observed several times both in the Fe-K and in the soft X-ray band. Resolve will be able for the first time to measure the velocity profiles of the absorption lines, and in the ideal case their inner kinematic structure, which will shed light on the physical nature of the wind. The high throughput of Resolve in the ideal case will further allow to measure the variability of the UFO over shorter time scales than ever before.

Our minimal goals are (1) to measure elemental abundances of the CSM and (2) to study electron-ion temperature nonequilibration. The CSM abundance will constrain the mass of the donor star in the progenitor system. If we are awarded 200 ks, then we will perform spatially-resolved spectroscopy, and we will reveal the CSM distribution. We will also clearly detect outermost ejecta materials, i.e., O and C (if present), from the southern rim, where the CSM contribution is much weaker than in the north. The amount of the outermost ejecta will allow us to infer explosion physics which also helps reveal the subclass of Kepler's SN.

Are they magnetically driven, connecting them to the jet as well as to the accretion process itself, or are they thermal/radiative, driven by X-ray irradiation of the outer disc? GX13+1 persistently shows a massive wind in absorption, and is the most reliable LMXRB wind source to address the key question of the origin of the wind. A 30ks Resolve observation can directly measure the wind velocity profile along the line of sight, which will distinguish between magnetic and thermal-radiative acceleration. An additional 80ks observation of 2S0921 will instead shows the wind in emission, as its very high inclination angle means the X-ray source is obscured by the disc.

Especially in single degenerate systems where the progenitor mass is near the Chandrasekhar mass limit, mass ratios among Fe-peak elements and Ti are greatly sensitive to the central density of the progenitor. Here we propose a XRISM observation of 3C 397, a remnant of single degenerate Type Ia supernova.

High resolution X-ray spectroscopy of SS 433 with Resolve gives unique opportunity to understand the jet structure at supercritical accretion rates.

It is persistent, and bright (0.25-0.75~Crab in soft X-rays), making it a popular testing ground for accretion flow models of all types. Among many other potential tests, observations with Resolve can reveal a warped disk, test models of binary evolution, and discover whether or not winds are launched from small disks in wind-fed systems. Studies related to the massive, 09.7 Iab supergiant companion wind in Cygnus X-1 are not the focus of this proposal, but issues central to massive stars can also be explored with Resolve. Apart from addressing important science, Cygnus X-1 is an important PV-phase test case for bright sources that will inform similar observations in normal mission cycles.

A large fraction of the merger energy is dissipated in the ICM, a process that depends on a number of unknown microphysical properties of the ICM. Resolve will provide the first opportunity to detect and map the bulk and turbulent velocities in the ICM of nearby merging systems. We propose to observe a textbook example of a cold front in A3667, a striking phenomenon caused by a merger. Resolve observations of this cold front would yield the bulk and turbulent velocities across the front, determining the origin of the front and providing a basis for the derivation of microphysical constraints from cold fronts, and answer a host of other interesting questions.
104 CYG X-3 308.10708 40.95775 PV A 40.000 TIMOTHY KALLMAN UNVEILING THE BLACK HOLE IN CYG X-3 We propose a 40 ks (minimal)/80 ks (ideal) observation of the unique and enigmatic high mass X-ray binary (HMXB) Cyg X-3. The iron line region in the Cyg X-3 spectrum contains hints of the dynamical effects of the black hole in this system. Improved measurements of the iron line radial velocity curve can be used to refine mass estimates for the black hole. In the soft state, there is surprising absorption from intermediate ion stages of iron, superimposed on a broad and complex emission. In the hard state the line is narrow and components of the line may have shifts indicative of the relativistic jet.

While the presence of CX X-ray emission from SNRs has been theoretically predicted, there is no robust evidence so far since conventional detectors cannot resolve cascade lines from higher excited states due to CX. Our recent observations of the Cygnus Loop with Suzaku and XMM-Newton revealed several promising results for the presence of CX. Here we propose to observe the remnant with XRISM for the purpose of a sure discovery of the CX for the first time from an SNR shell.

111 SS CYGNI 325.67829 43.58611 PV A 100.000 MANABU ISHIDA OBSERVATIONS OF SS CYGNI IN QUIESCENCE AND OUTBURST SS Cygni is one of the prototypical dwarf novae, which shows transitions between an optically quiescent state and an outburst state. In the outburst state, hard X-ray emission is thought to arise from coronae over an accretion disc, but their location is unclear. We will understand the corona geometry by measuring profiles of the coronal emission lines with the Resolve. In the quiescent state, on the other hand, it is commonly understood that the hard X-ray emission emanates from the optically thin boundary layer, yet its heating mechanism and radial profile of the BL plasma are both poorly understood. We will try to make them clear by means of spectroscopy of the emission lines from the plasma and the fluorescent iron K-alpha emission line with the Resolve.

113 CYG X-2 326.17146 38.34808 PV C 40.000 LIA CORRALES HOW DOES INTERSTELLAR OXYGEN AND IRON BECOME SOLID? High resolution X-ray spectroscopy can probe the chemical composition and mineral structure of solid interstellar material in situ, more directly than any other wavelength, by observing X-ray absorption fine structure (XAFS). XAFS features produce complementary X-ray scattering fine structure (XSFS), which is imprinted on the spectrum of the dust scattering halos that are seen around bright Galactic point sources. We propose Resolve observations of the Cyg X-2 dust scattering halo that will measure XSFS from: (i) solid interstellar Oxygen, the most abundant interstellar metal, observed to easily change between solid and gas phases in the ISM, and (ii) solid interstellar Iron, a highly depleted heavy metal with an unknown pathway for incorporation into interstellar dust.

133 CAS A E/JET 350.92825 58.83358 PV A 50.000 JACCO VINK OBSERVING CAS A WITH XRISM: FROM A SUPERNOVA'S INNER WORKINGS TO THE IMPRINTS OF COSMIC-RAY ACCELERATION Cas A is the archetypal young core-collapse SNR, with X-ray knots dominated by O-, Si-, and Fe-rich plasma, and a pair of Si-rich jets. Cas A is a bright source of IR dust emission. The primary observational goals are to detect emission from Na, Al, P, Cl, K, Cr in different ejecta layers, and spectral dust signatures: fluorescence lines, and low ionisation Si and Mg continuously injected into the plasma by grain sputtering. This results in a red tail to Mg/Si K-lines, in contrast to Ne/S K-lines. Secondary goals are accurate mapping of plasma parameters, and measuring Doppler shifts/broadening due to bulk motion and thermal broadening. Previous results based on centroiding were affected by varying line-blends, which can be disentangled by Resolve.
