Quenching of Satellite Galaxies at the Outskirts of Galaxy Clusters

Date 9 Oct 2016
AbstractWe find, using cosmological simulations of galaxy clusters, that the hot X-ray emitting intra-cluster medium (ICM) enclosed within the outer accretion shock extends out to $R_{ m shock}sim(2 - 3) R_{ m vir}$, where $R_{ m vir}$ is the standard virial radius of the halo. Using a simple analytic model for satellite galaxies in the cluster, we evaluate the effect of ram-pressure stripping on the gas in the inner discs and in the haloes at different distances from the cluster centre. We find that significant removal of star-forming disc gas occurs only at $r lesssim 0.5 R_{ m vir}$, while gas removal from the satellite halo is also efficient between $R_{ m vir}$ and $R_{ m shock}$. This leads to quenching of star formation by starvation over $2-3,{ m Gyr}$, prior to the satellite entry to the inner cluster halo. This can explain the presence of quenched galaxies, preferentially discs, at the outskirts of galaxy clusters, and the delayed quenching of satellites compared to central galaxies.
