17 Sep 1997 | | Subject: | astro-ph | | Affiliation: | State University of New York at Stony Brook), Alberto Fernandez-Soto (State University of New York at Stony Brook), and Amos Yahil (State University of New York at Stony Brook | | Abstract: | We describe our application of broad-band photometric redshift techniques to faint galaxies in the Hubble Deep Field. To magnitudes AB(8140) < 26, the accuracy of the photometric redshifts is a few tenths and the reliability of the photometric redshifts approaches 100%. At fainter magnitudes the effects of photometric error on the photometric redshifts can be rigorously quantified and accounted for. We argue that broad-band photometric redshift techniques can be applied to accurately and reliably estimate redshifts of galaxies that are up to many magnitudes fainter than the spectroscopic limit. | | Source: | arXiv, astro-ph/9709166 | | Services: | Forum | Review | PDF | Favorites | |
