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…
Electron-Ion Equilibration in the Merging Galaxy Cluster A665
Christian Norseth, Daniel R. Wik, Craig L. Sarazin +2
Galaxy cluster mergers drive powerful shock fronts that heat the intracluster medium (ICM) and accelerate particles, redistributing the energy in a merger. A665 is one of only a fe…
Comparing XRISM cluster velocity dispersions with predictions from cosmological simulations: are feedback models too ejective?
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +147
The dynamics of the intra-cluster medium (ICM), the hot plasma that fills galaxy clusters, are shaped by gravity-driven cluster mergers and feedback from supermassive black holes (…
The structure of the giant radio fossil in the Ophiuchus galaxy cluster
Simona Giacintucci, Maxim Markevitch, Tracy Clarke +1
We present high-sensitivity follow-up observations of the giant fossil radio lobe in the Ophiuchus galaxy cluster with the upgraded Giant Metrewave Radio Telescope (uGMRT) in the 1…
