CHEX-MATE: X-ray surface brightness discontinuities across a representative cluster sample

Maria Giulia Campitiello, Stefano Ettori, Lorenzo Lovisari +20

We analyze the presence of X-ray surface brightness (SB) discontinuities, such as shocks and cold fronts, in the intracluster medium (ICM) of the 116 galaxy clusters from the CHEX-…

High-statistics simulations of NewAthena WFI background using Geant4

Matthew K. Heine, Catherine E. Grant, Marshall W. Bautz +14

The observation of hot gas structures is one science goal of the Wide Field Imager (WFI) on ESA's NewAthena X-ray observatory. Because the measurement of these faint diffuse source…

Galaxy clusters in the LoTSS-DR3: Catalogues and detection pipeline for diffuse radio emission

C. Stuardi, G. Di Gennaro, A. Botteon +19

The third data release of the LOFAR Two-metre Sky Survey provides an unprecedented view of the northern sky at 144 MHz. While compact sources can be efficiently identified with aut…

Simulation-Based Cosmological Mass Calibration of XXL Galaxy Clusters using HSC Weak Lensing

Sut-Ieng Tam, Keiichi Umetsu, Adam Amara +13

We present a cosmological analysis of the X-ray-selected galaxy cluster sample from the XXL survey, employing a simulation-based inference (SBI) framework to jointly constrain cosm…

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…

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…
