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…

The SRG/eROSITA All-Sky Survey: Constraints on AGN Feedback in Galaxy Groups
Y. E. Bahar, E. Bulbul, V. Ghirardini +25
We investigate the impact of AGN feedback, on the entropy and characteristic temperature measurements of galaxy groups detected in the SRG/eROSITA's first All-Sky Survey (eRASS1) t…

Gas thermodynamics meets galaxy kinematics: Joint mass measurements for eROSITA galaxy clusters
Pengfei Li, Ang Liu, Matthias Kluge +13
The mass of galaxy clusters is a critical quantity for probing cluster cosmology and testing theories of gravity, but its measurement could be biased given assumptions are inevitab…
