Binary interactions and UV photometry on photometric redshift
Abstract
Using the Hyperz code (Bolzonella et al. 2000) we present photometric redshift estimates for a random sample of galaxies selected from the SDSS/DR7 and GALEX/DR4, for which spectroscopic redshifts are also available. We confirm that the inclusion of ultraviolet photometry improves the accuracy of photo-zs for those galaxies with g*-r* < 0.7 and zspec < 0.2. We also address the problem of how binary interactions can affect photo-z estimates, and find that their effect is negligible.
