abstract
This white paper was prepared by members of the XRISM Science Team for the benefit of the general astronomical community. This paper describes the capabilities of XRISM, offers a sampling of the many science topics that the mission will address, and discusses the synergies of XRISM with the plethora of planned and existing facilities in the 2020s and beyond.

Fe Kα lines from accreting black holes are produced mostly outside 10 gravitational radii due to radial ionization gradients, allowing broad profiles without high spin.
Simulation analysis of 415 clusters reveals two accretion regimes: warm filament gas enters slowly thermalizing at 2-4 R200 while tangential velocity gradients and hot gas ejection appear at 1-2 R200, with no strong filament accretion shocks.
The two correction approaches differ in their radial dependence in 3D but agree to within a few percent in projected observations, with the non-thermal pressure fraction underestimated by a factor of about 2.
Bayesian fitting of NICER comet X-ray data identifies three spectral families and shows carbon-derived freeze-in temperatures lower than those from nitrogen and oxygen lines, with short-term variability attributed to solar-wind charge-state changes.
DIXE NXB averages 4.46e-2 counts s^-1 cm^-2 keV^-1 at the geomagnetic equator under solar minimum, dominated by cosmic-proton-induced particles, rising to 1.55e-1 at higher latitudes, with SAA delayed background negligible after ~5 minutes.
