Phase-resolved high-resolution spectroscopy of M82 X-2 with XRISM Resolve finds broader Fe Kα line during pulse peak, indicating origin in the accretion flow with velocity dispersion of about 1700 km/s.
XRISM/Resolve data on Mrk 509 show a tentative 3.6-sigma infalling absorber at 11000 km/s located within thousands of gravitational radii, interpreted as raining clumps from a failed wind.
XRISM/Resolve high-resolution spectroscopy detects coherent orbital modulation in Fe XXV Kα line centroids from EX Hydrae, yielding K1 = 58.1 km/s and a white dwarf mass of 0.79 solar masses consistent with optical tracers.
XRISM spectroscopy of NGC 4388 shows the Fe Kα line arising from the torus, inner torus edge, and BLR at distinct radii, with absorption revealing a gravitationally bound failed wind.
