Spectrally Resolved Gas Kinematics in Cygnus A: XRISM Detects AGN Jet-induced Velocity Dispersion in Multitemperature Gas

We report spectral analysis on a 170 ks XRISM Resolve exposure of the core of Cygnus A. Analyzing the full field of view spectrum in the 1.7–12.0 keV band, we find evidence for two-temperature cluster gas. The hotter ( kT  = 5.53 ± 0.13 keV) gas has a velocity dispersion of 261 ± 13 km s ^−1 and a b...
