MIPS 70-micron Observations of the Spitzer Extragalactic First Look Survey

Abstract

Early results from the 70-micron observations of the Spitzer Extragalactic First Look Survey are presented. As a whole, about 90% of the population show infrared colors that are consistent with the spectral energy distributions of the local IRAS population of luminous infrared starbursts, while approximately 10% of the sample show warm infrared colors consistent with AGN activity. The mean redshift for the population is z=0.2, and the mean total infrared luminosity is about L(ir)= 2x10^{11} L(sun).
