The SLUGGS Survey: revisiting the correlation between X-ray luminosity and total mass of massive early-type galaxies

Abstract

Here we utilise recent measures of galaxy total dynamical mass and X-ray gas luminosities (L${}_{X,Gas}$) for a sample of 29 massive early-type galaxies from the SLUGGS survey to probe L${}_{X,Gas}$--mass scaling relations. In particular, we investigate scalings with stellar mass, dynamical mass within 5 effective radii (R${}_e$) and total virial mass. We also compare these relations with predictions from $\Lambda$CDM simulations. We find a strong linear relationship between L${}_{X,Gas}$ and galaxy dynamical mass within 5 R${}_e$, which is consistent with the recent cosmological simulations of Choi et al. that incorporate mechanical heating from AGN. We conclude that the gas surrounding massive early-type galaxies was shock heated as it fell into collapsing dark matter halos so that L${}_{X,Gas}$ is primarily driven by the depth of a galaxy's potential well. Heating by an AGN plays an important secondary role in determining L${}_{X,Gas}$.
