Spitzer Observations of the SCUBA/VLA Sources in the Lockman Hole: Star Formation History of Infrared-Luminous Galaxies Academic Article uri icon


  • We present Spitzer Space Telescope imaging observations at 3.6, 4.5, 5.8, 8.0, and 24 m of the SCUBA submillimeter sources and Jy VLA radio sources in a 5 x 5 area in the Lockman Hole East region. Out of the 40 SCUBA/VLA sources in the field, Spitzer counterparts were detected for nearly all except for the few low-weight SCUBA detections. We show that the majority (80%-90%) of the detected sources are cold (i.e., starburst-like) infrared-luminous galaxies (L IR > 10 11 L ) at redshift 0.5 < z < 3.5, whose star-formation rate density (SFRD) is comparable to that of the optically selected star-forming galaxies.
