We report on submillimeter and infrared observations of 28 radio-selected galaxies in the Spitzer First Look Survey Verification field ( FLSV ) .
All of the radio-selected galaxies that show evidence for emission at 850 \mu m with SCUBA have Spitzer counterparts at 24 \mu m , while only half of the radio-selected galaxies without 850 \mu m emission have detectable counterparts at 24 \mu m. The data show a wide range of infrared colors ( S70/S24 < 5 –30 , S8/S3.6 < 0.3 –4 ) , indicative of a mixture of infrared-warm AGN and cooler starburst dominated sources .
The galaxies showing 850 \mu m 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 .
