Correcting the hydrostatic mass for non-thermal gas motions: a comparison of two approaches
Théo Lebeau, Nabila Aghanim, Jenny Sorce +1
An accurate estimation of the mass of galaxy clusters is key to precisely and unbiasedly constraining cosmological parameters through their number count. The hydrostatic mass, esti…
Simulating the LOcal Web (SLOW) V. Thermodynamic Properties and Evolution of Local Galaxy Clusters
Elena Hernández-Martínez, Klaus Dolag, Ulrich P. Steinwandel +4
The intracluster medium (ICM), composed of hot plasma, dominates the baryonic content of galaxy clusters and is primarily observable in X-rays. Its thermodynamic properties, pressu…
Gas motion in the intracluster medium of the Virgo cluster replica
Théo Lebeau, Stefano Ettori, Jenny G. Sorce +2
Within the deep gravitational potential of galaxy clusters lies the intracluster medium (ICM). At the first order, it is considered to be at hydrostatic equilibrium within the pote…
Velocity fields and turbulence from cosmic filaments to galaxy clusters
Théo Lebeau, Saleem Zaroubi, Nabila Aghanim +2
Galaxy clusters are currently the endpoint of the hierarchical structure formation; they form via the accretion of dark matter and cosmic gas from their local environment. In parti…
Can the splashback radius be an observable boundary of galaxy clusters?
Théo Lebeau, Stefano Ettori, Nabila Aghanim +1
The splashback radius was proposed as a physically motivated boundary of clusters as it sets the limit between the infalling and the orbitally dominated regions. However, galaxy cl…
