Revealing the differences in the SMBH accretion rate distributions of starburst and non-starburst galaxies

Abstract

We infer and compare the specific X-ray luminosity distributions for a sample of massive (i.e. ${\log }_{10}(M\ast /M\odot )>10.5$) galaxies split according to their far-infrared-derived star-forming properties (i.e., starburst and non-starburst) and redshift. We model each distribution as a power-law with an upper and lower turnover, and adopt a maximum likelihood method to include information from non-detections in the form of upper limits. When we use our inferred distributions to calculate the ratios of high to low sLx AGN (corresponding to above and below $0.1{\lambda }_{\text{Edd}}$, respectively) we find that starbursts have significantly higher proportions of high sLx AGN compared to their non-starburst counterparts. These findings help explain the increase in average X-ray luminosity in bins of increasing SFR reported by previous studies.
