Deep GMOS Spectroscopy of Faint SWIRE Populations
Abstract
We have carried out a deep (21.5<R<23.9) systematic survey of galaxies selected from SWIRE using GMOS to target X-ray sources, AGN and galaxies with photometric redshifts greater than 1. We have obtained a total of 198 redshifts, of which 132 have secure redshifts in the range 0.12<z<1.21. This sample, combined with the 111 redshifts targeted with WIYN in the same field and the 1 square degree survey of ELAIS-N1 with ACIS-I, will allow us to calibrate our photometric redshift techniques; characterise the star formation history of the universe between 0.5<z<1.2 where galaxy formation activity peaks; and explore the connection between AGN and star-formation activity.
