X-ray spectroscopy of hot dense plasmas using LLNL's upgraded Titan 2 short-pulse laser

A. J. Fairchild, D. T. Bishel, T. Cordova +10

We are developing an experimental platform at Lawrence Livermore National Laboratory's Jupiter Laser Facility to characterize X-ray emission from highly charged ions in the high-de…

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…

XRISM constraints on unidentified X-ray emission lines, including the 3.5 keV line, in the stacked spectrum of ten galaxy clusters

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +150

We stack 3.75 Megaseconds of early XRISM Resolve observations of ten galaxy clusters to search for unidentified spectral lines in the 2.5-15 keV band (rest frame), including t…

Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations

XRISM Collaboration

Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…

The XRISM/Resolve view of the Fe K region of Cyg X-3

XRISM Collaboration

The X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes th…

Temperature Structure in the Perseus Cluster Core Observed with Hitomi

Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +192

The present paper investigates the temperature structure of the X-ray emitting plasma in the core of the Perseus cluster using the 1.8--20.0 keV data obtained with the Soft X-ray S…

Hitomi constraints on the 3.5 keV line in the Perseus galaxy cluster

Hitomi Collaboration, Felix A. Aharonian, Hiroki Akamatsu +215

High-resolution X-ray spectroscopy with Hitomi was expected to resolve the origin of the faint unidentified E=3.5 keV emission line reported in several low-resolution studies of va…
