Tracing the non-thermal pressure and hydrostatic bias in galaxy clusters
S. Ettori, D. Eckert
We present a modelization of the non-thermal pressure, , and we apply it to the X-ray (and Sunayev-Zel'dovich) derived radial profiles of the X-COP galaxy clusters. We rela…
Characterizing the bulk and turbulent gas motions in galaxy clusters
Simon Dupourqué, Etienne Pointecouteau, Nicolas Clerc +1
The most massive halos of matter in the Universe grow via accretion and merger events throughout cosmic times. These violent processes generate shocks at many scales and induce lar…
Reconstructing AGN X-ray spectral parameter distributions with Bayesian methods II: Population inference
Lingsong Ge, Stéphane Paltani, Dominique Eckert +1
We present a new Bayesian method for reconstructing the parent distributions of X-ray spectral parameters of active galactic nuclei (AGN) in large surveys. The method uses the prob…
Reconstructing AGN X-ray spectral parameter distributions with Bayesian methods I: Spectral analysis
Lingsong Ge, Stéphane Paltani, Dominique Eckert
X-ray spectra of active galactic nuclei (AGN) consist of several different emission and absorption components, which are often fitted manually with models chosen on a case-by-case…
HSC-XXL : Baryon budget of the 136 XXL Groups and Clusters
Daichi Akino, Dominique Eckert, Nobuhiro Okabe +17
We present our determination of the baryon budget for an X-ray-selected XXL sample of 136 galaxy groups and clusters spanning nearly two orders of magnitude in mass ($M_{500}\sim 1…
The XXL survey: XLVI. Forward cosmological analysis of the C1 cluster sample
Christian Garrel, Marguerite Pierre, Patrick Valageas +15
We present the forward cosmological analysis of an selected sample of galaxy clusters out to a redshift of unity. Following our previous 2018 study based on the dn/dz quantit…
