    Yan, Lin; Helou, G.; Fadda, D.; Marleau, F. R.; Lacy, M.; Wilson, G.; Soifer, B. T.; Drozdovsky, I.; Masci, F.; Armus, L.; Teplitz, H. I.; Frayer, D. T.; Surace, J.; Storrie-Lombardi, L. J.; Appleton, P. N.; Chapman, S.; Choi, P.; Fan, F.; Heinrichsen, I.; Im, M.; Schmitz, M.; Shupe, D. L.; Squires, G. K. (2004-09)
    In this Letter, we present the initial characterization of extragalactic 24um sources in the Spitzer First Look Survey (FLS) by examining their counterparts at 8um and R-band. The color-color diagram of 24-to-8 vs. 24-to-0.7um ...

  • Infrared Properties of Radio-Selected Submillimeter Galaxies in the Spitzer First Look Survey Verification Field 

    Frayer, D. T.; Chapman, S. C.; Yan, L.; Armus, L.; Helou, G.; Fadda, D.; Morganti, R.; Garrett, M. A.; Appleton, P.; Choi, P.; Fang, F.; Heinrichsen, I.; Im, M.; Lacy, M.; Marleau, F.; Masci, F. J.; Shupe, D. L.; Soifer, B. T.; Squires, G. K.; Storrie-Lombardi, L. J.; Surace, J. A.; Teplitz, H. I.; Wilson, G. (2004-09)
    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 850um ...
