Abstract: Aims.We explore the connection between black hole growth at the center of obscured quasars selected from the XMM-COSMOS survey and the physical properties of their host galaxies. We study a bolometric regime ( ⟨ Lbol⟩  = 8  ×  1045erg s-1) where several theoretical models invoke major galaxy mergers as the main fueling channel for black hole accretion.
