| Abstract | We introduce a new empirical function for modeling the spectral energy distributions (SEDs) of galaxies. We apply it to a sample of 590 galaxies in the region of the Hubble Deep Field (HDF) with z<1.5 using multicolor photometry with wide wavelength coverage combined with spectroscopic redshifts from our 93% complete R-selected redshift survey there. We find the following:1. As expected, galaxies with strong signs of recent star formation (i.e., those that show emission lines) have bluer continua in both the rest-frame ultraviolet and optical/near-infrared.2. The redder galaxies tend to be more luminous. Although galaxies with strong absorption lines and no emission features are ~15% of the total sample with 0.25 |
