The Three Hundred project: Low Gas Fraction Galaxy Clusters properties and their environment
Francesco Guidi, Marco De Petris, Sara Santoni +7
Galaxy cluster samples based on X-ray and Sunyaev-Zel'dovich (SZ) observations are affected by selection biases. These catalogs preferentially include systems with high gas content…

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…
