Scientific paper

Type II quasars are the luminous analogues of Type II Seyferts; the central engines are presumably heavily obscured by dust. We have defined a sample of 9 highly luminous Type II quasar candidates with 0.24 < z < 0.40 from the spectroscopic data of the Sloan Digital Sky Survey, which have high equivalent width, narrow emission-line spectra characteristic of a nonthermal continuum. We estimate that the obscured AGN in these objects have optical luminosities of order 1012 solar luminosities. We propose to image this sample in rest-frame U, B and V, to determine the morphology and color of the host galaxies, and look for recent star formation. We will also probe the extended environments of these objects, to determine whether they are undergoing interactions with close companions, and whether they live in appreciably clustered environments.
