A Highly Complete Spectroscopic Survey of the GOODS-N Field
Abstract
We present a table of redshifts for 2907 galaxies and stars in the 145 arcmin2 HST ACS GOODS-North, making this the most spectroscopically complete redshift sample obtained to date in a field of this size. We also include the redshifts, where available, in a table containing just under 7000 galaxies from the ACS area with Ks, AB < 24.5 measured from a deep Ks image obtained with WIRCam on the CFHT, as well as in a table containing 1016 sources with NUVAB < 25 and 478 sources with FUVAB < 25.5 (there is considerable overlap) measured from the deep GALEX images in the ACS area. Finally, we include the redshifts, where available, in a table containing the 1199 24 μm sources to 80 μJy measured from the wider area Spitzer GOODS-North. The redshift identifications are greater than 90% complete to magnitudes of F 435WAB = 24.5, F 850LPAB = 23.3, and Ks, AB = 21.5, and to 24 μm fluxes of 250 μJy. An extensive analysis of these data appear in a companion paper, but here we test the efficiency of color-selection techniques to identify populations of high-redshift galaxies and active galactic nuclei. We also examine the feasibility of doing tomography of the intergalactic medium with a 30 m telescope.
