Infrared Properties of Radio‐selected Submillimeter Galaxies in the Spitzer First Look Survey Verification Field
Abstract
We report on submillimeter and infrared observations of 28 radio-selected galaxies in the Spitzer First Look Survey verification field. All of the radio-selected galaxies that show evidence for emission at 850 μm with SCUBA have Spitzer counterparts at 24 μm, while only half of the radio-selected galaxies without 850 μm emission have detectable counterparts at 24 μm. The data show a wide range of infrared colors (S_(70 μm)/S_(24 μm) < 5-30, S_(8 μm)/S_(3.6 μm) < 0.3-4), indicative of a mixture of infrared-warm AGN-dominated and cooler starburst-dominated sources. The galaxies showing 850 μm emission have Spitzer flux densities and flux density ratios consistent with the range of values expected for high-redshift (z = 1-4) ultraluminous infrared galaxies.
