The major cluster merger in Abell 2034 as seen by XRISM: Strong turbulence and spectral anomalies?
Annie Heinrich, Irina Zhuravleva, Eugene Churazov +5
XRISM observations to date have shown that gas kinetic pressures in the intracluster medium (ICM) tend towards the low end of predictions from cosmological simulations. Here, we pr…

The LOFAR sub-arcsecond view of the high-redshift radio relic in PSZ2G091.83+26.11
G. Di Gennaro, R. Timmerman, M. Hoeft +14
Enhanced inverse Compton (IC) losses at high redshift steepen diffuse radio spectra in galaxy clusters, making low-frequency (~100 MHz) observations favorable. However, low-frequen…

Deep Chandra observations of PLCKG287.0+32.9: a clear detection of a shock front in a heated former cool core
M. Gitti, A. Bonafede, F. Brighenti +9
The massive, hot galaxy cluster PSZ2 G286.98+32.90 (hereafter PLCKG287, z=0.383) hosts a giant radio halo and two prominent radio relics which are signs of a disturbed dynamical st…
