Most supermassive black hole growth is obscured by dust
Alejo Martinez-Sansigre, Steve Rawlings, Mark Lacy +5
We present an alternative method to X-ray surveys for hunting down the high-redshift type-2 quasar population, using Spitzer and VLA data on the Spitzer First Look Survey. By deman…
The TOOT00 Redshift Survey of Radio Sources
Eleni Vardoulaki, Steve Rawlings, Gary J. Hill +4
We present first results from the study of the TOOT00 region consisting of 47 radio sources brighter than 100 mJy at 151 MHz. We have 81% spectroscopic redshift completeness. From…
The SCUBA HAlf Degree Extragalactic Survey (SHADES) -- I. Survey motivation, design and data processing
A. M. J. Mortier, S. Serjeant, J. S. Dunlop +2
The SCUBA HAlf Degree Extragalactic Survey (SHADES) is a major blank-field extragalactic sub-mm survey underway at the James Clerk Maxwell telescope.SHADES aims to cover half a squ…
First results from the Canada-France High-z Quasar Survey: Constraints on the z=6 quasar luminosity function and the quasar contribution to reionization
Chris J. Willott, Xavier Delfosse, Thierry Forveille +2
We present preliminary results of a new quasar survey being undertaken with multi-colour optical imaging from the Canada-France-Hawaii Telescope. The current data consists of 3.83…
No evidence of "gray" dust from composite quasar spectra
Chris J. Willott
Two recent studies based on composite reddened quasar spectra have indicated the presence of `gray' dust in quasar environments. This gray dust has a relatively flat extinction law…
Imaging of SDSS z>6 quasar fields: gravitational lensing, companion galaxies and the host dark matter halos
Chris J. Willott, Will J. Percival, Ross J. McLure +5
We have undertaken deep optical imaging observations of three 6.2<z<6.5 quasar fields in the i' and z' filters. These data are used to search for foreground galaxies which are grav…
