| Abstract: |
Using mid-infrared and radio criteria, we select a sample of candidate z ~ 2 obscured quasars. Optical spectroscopy confirms about half of these as type 2 quasars, and modelling the population suggests 50–80% of the quasars are obscured. We find some flat radio spectrum type 2 quasars, and tentative evidence for obscuration unrelated to the torus. Using a similar sample, we also find evidence for a significant fraction of Compton-thick quasars. |
