Heavily Obscured Quasar Host Galaxies at z~2 are Disks, Not Major Mergers
HST WFC3/IR imaging of 28 Dust Obscured Galaxies (DOGs) We find that only a small fraction (4%, at most11-25%) of the quasar host galaxies are major mergers.
Finally, we suggest that the co-incidence of mergers and AGNactivity is luminosity dependent, with only the most luminous quasars beingtriggered mostly by major mergers.
