The Three Hundred project: cosmic web identification from 2D gas and Compton- maps of galaxy clusters outskirts
Sara Santoni, Marco De Petris, Gustavo Yepes +4
Galaxy clusters are located at the nodes of the filamentary network known as the cosmic web. A more comprehensive understanding of galaxy clusters can be achieved by considering th…
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…
Galaxy cluster temperature maps from joint X-ray and SZ maps with The Three Hundred hydrodynamical simulations
R. Wicker, M. De Petris, A. Ferragamo +8
Galaxy clusters can be used as powerful cosmological probes, provided one can obtain accurate mass estimates, which requires a precise knowledge of the underlying astrophysics of g…
Constraining hydrostatic mass bias and cosmological parameters with the gas mass fraction in galaxy clusters
Raphaël Wicker, Marian Douspis, Laura Salvati +1
The gas mass fraction in galaxy clusters is a convenient tool to use in the context of cosmological studies. Indeed this quantity allows to constrain the universal baryon fraction…
