Evidence for a large fraction of Compton-thick quasars at high redshift
Alejo Martinez-Sansigre, Steve Rawlings, David G. Bonfield +7
Using mid-infrared and radio selection criteria, we pre-select a sample of candidate high-redshift type-2 quasars in the Subaru XMM-Newton Deep Field (SXDF). To filter out starburs…
Molecular gas observations of the reddened quasar 3C 318
Chris J. Willott, Alejo Martinez-Sansigre, Steve Rawlings
3C 318 is a z=1.574 radio-loud quasar. The small physical size of its radio jets indicate that these jets were triggered relatively recently. In addition to the ultraviolet continu…
Radio imaging of the Subaru/XMM-Newton Deep Field - I. The 100-microJy catalogue, optical identifications, and the nature of the faint radio source population
Chris Simpson, Alejo Martinez-Sansigre, Steve Rawlings +6
We describe deep radio imaging at 1.4-GHz of the 1.3 square degree Subaru/XMM-Newton Deep Field (SXDF), made with the Very Large Array in B and C configurations. We present a radio…
A population of high-redshift type-2 quasars-II. Radio Properties
Alejo Martinez-Sansigre, Steve Rawlings, Timothy Garn +4
We present multi-frequency radio observations of a sample of z~2 obscured (type-2) quasars in the Spitzer extragalactic First Look Survey area. We combine the public data at 1.4 GH…
A population of high-redshift type-2 quasars-I. Selection Criteria and Optical Spectra
Alejo Martinez-Sansigre, Steve Rawlings, Mark Lacy +5
We discuss the relative merits of mid-infrared and X-ray selection of type-2 quasars. We describe the mid-infrared, near-infrared and radio selection criteria used to find a popula…
