X-ray Doppler tomography of Fe K emission in a low-mass X-ray binary 4U 1822-371 - a localized reflector at the accretion stream-disk overflow
N. Sameshima, M. Tsujimoto, M. Uemura
We present the X-ray Doppler tomography of the Fe K (6.4 keV) fluorescence line of the low-mass X-ray binary 4U 1822-371 obtained with XRISM. Eleven orbits of this short period…

A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87
XRISM Collaboration, M. Audard, H. Awaki +138
The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…

Optimization of x-ray event screening using ground and in-orbit data for the Resolve instrument onboard the XRISM satellite
Yuto Mochizuki, Masahiro Tsujimoto, Caroline A. Kilbourne +9
The XRISM (X-Ray Imaging and Spectroscopy Mission) satellite was successfully launched and put into a low-Earth orbit on September 6, 2023 (UT). The Resolve instrument onboard XRIS…
