Non-parametric estimation of the baryon gas fraction and the cosmological bias with clusters
Hyeon Kim, Raphaël Wicker, Benjamin L'Huillier +3
X-ray observations of galaxy clusters allow us to estimate the gas fraction, and thus the baryon fraction, and its evolution over time. This offers an additional cosmological probe…

Implications of SPT and eROSITA cosmologies for Planck cluster number counts and t-SZ power spectrum
G. Aymerich, M. Douspis, N. Battaglia +4
Comparison between cosmological studies is usually performed in a statistical manner at the level of the posteriors of cosmological parameters. In this Letter, we show how this app…
