High-statistics simulations of NewAthena WFI background using Geant4
Matthew K. Heine, Catherine E. Grant, Marshall W. Bautz +14
The paper presents high‑statistics Geant4 simulations of the background caused by cosmic‑ray interactions in the Wide Field Imager of ESA's NewAthena X‑ray observatory, using both…
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…
Non-thermal filaments and AGN recurrent activity in the galaxy group Nest200047: a LOFAR, uGMRT, MeerKAT, VLA radio spectral analysis
M. Brienza, K. Rajpurohit, E. Churazov +15
Nest200047 is a clear example of multiple radio bubbles from an Active Galactic Nucleus (AGN) in a galaxy group, featuring non-thermal filaments likely shaped by buoyancy, gas moti…
