Offset between X-ray and optical centers in clusters of galaxies: connecting eROSITA data and simulations
R. Seppi, J. Comparat, K. Nandra +6
The characterization of the dynamical state of clusters is key to study their evolution, their selection, and use them as a cosmological probe. The offsets between different defini…
Effects of Multiphase Gas and Projection on X-ray Observables in Simulated Galaxy Clusters as Seen by eROSITA
J. ZuHone, Y. E. Bahar, V. Biffi +8
The number density of galaxy clusters as a function of mass and redshift is a sensitive function of the cosmological parameters. To use clusters for cosmological parameter studies,…
X-ray analysis of JWST's first galaxy cluster lens SMACS J0723.3-7327
A. Liu, E. Bulbul, M. E. Ramos-Ceja +10
SMACS~J0723.3-7327 is the first galaxy cluster lens observed by JWST. Based on the ERO data from JWST, several groups have reported the results on strong lensing analysis and mass…
Hydrostatic Mass Profiles of Galaxy Clusters in the eROSITA Survey
Dominik Scheck, Jeremy S. Sanders, Veronica Biffi +3
To assume hydrostatic equilibrium between the intracluster medium and the gravitational potential of galaxy clusters is an extensively used method to investigate their total masses…
Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
Discovery of a pre-merger shock in an intercluster filament in Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +11
We report the first unambiguous detection of an axial merger shock in the early-stage merging cluster Abell 98 using deep (227 ks) Chandra observations. The shock is about 420 kpc…
