Star Forming Galaxies: Properties and Implications for the Extragalactic Infrared Background

Open full text 3 citations

Abstract

This paper reviews those properties of normal galaxies most relevant to the estimation of the extragalactic infrared background, in particular: (1) their infrared emission spectrum and its variation among galaxies; (2) their morphological properties, and their infrared size distribution in comparison to their apparent visible-light sizes; and (3) other properties such as the infrared-to-radio ratio and color-luminosity relations. Even a simple comparison of those properties to those of the extragalactic infrared background leads to constraints on the fluctuations in time and the secular evolutionary behavior of the infrared luminosity of galaxies.
