Abstract
- We found that the rapid decline of SFR density from z = 1 to z = 0 is accompanied by a rapid decline of the contribution of infrared (IR) galaxies [1]. Making use of FUV (GALEX) and FIR (IRAS/Spitzer) data, we have established a method to estimate the star-formation luminosity function (LF), that is a LF of galaxy luminosity produced by newly formed stars [1]. In this work, we have calculated the distribution function of SFR of galaxies (SFR function) as a function of redshift at z = 0–1 from UV and FIR selected galaxies in the CDFS. We found that, though the FUV- and FIR-based SFR functions agree until z = 0.7, the FUV-based one becomes significantly lower than FIR based one at z = 1. As for integrated value, this means that the SFR density is at least 40% underestimated, even after adding the contribution from obscured star formation. [ABSTRACT FROM AUTHOR]
