XRISM Reveals a Kinematically Coherent Core System of the Nearby Cool-Core Cluster Abell 2199
Kazunori Suda, Kyoko Matsushita, Kosuke Sato +14
We present the results of a deep 251 ks XRISM/Resolve observation of the cool core of the galaxy cluster Abell 2199. From the integrated spectrum of the central Reso…
XRISM Observations of Abell 1795: Evidence for Low Turbulence and Resonant Scattering
Arnab Sarkar, Eric D. Miller, Brian McNamara +10
We present high-resolution X-ray spectroscopic observations of the cool-core galaxy cluster Abell~1795 obtained with XRISM/Resolve. The cluster was observed with two deep pointings…
X-ray evidence from NuSTAR for a Mach 3 shock in Merging Galaxy Cluster ZWCL 1856.8
AyÅegül Tümer, Christian T. Norseth, Daniel R. Wik
We present spectral analysis results of deeper (270 ks) NuSTAR observations of the merging galaxy cluster system, ZWCL1856.8+6616, at redshift z=0.304, following a pilot study usin…
Cross Calibration of Galaxy Cluster Temperatures Measured with NuSTAR, XMM-Newton, and Chandra
Fiona Lopez, Daniel R. Wik, Cicely Potter +10
The use of galaxy clusters to constrain cosmology is limited in part due to uncertainties in derived cluster masses, which often depend on the gas temperature. Unfortunately, there…
The Distribution of Hard X-ray Selected AGN in the NEP Field
Samantha Creech, Francesca Civano, Daniel R. Wik +9
X-ray surveys are one of the most unbiased methods for detecting Compton Thick (CT; cm) AGN, which are thought to comprise up to of AGN…
XRISM constraints on the velocity power spectrum in the Coma cluster
D. Eckert, M. Markevitch, J. A. ZuHone +6
The velocity field of intracluster gas in galaxy clusters contains key information on the virialization of infalling material, the dissipation of AGN energy into the surrounding me…
