  • Characterization of Extragalactic 24micron Sources in the Spitzer First Look Survey 

    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 ...

  • Extragalactic Source Counts at 24 Microns in the Spitzer First Look Survey 

    Marleau, Francine R.; Fadda, D.; Storrie-Lombardi, L. J.; Helou, G.; Makovoz, D.; Frayer, D. T.; Yan, L.; Appleton, P. N.; Armus, L.; Chapman, S.; Choi, P. I.; Fang, F.; Heinrichsen, I.; Im, M.; Lacy, M.; Shupe, D.; Soifer, B. T.; Squires, G.; Surace, J.; Teplitz, H. I.; Wilson, G. (2004-09)
    We present the Spitzer MIPS 24 micron source counts in the Extragalactic First Look Survey main, verification and ELAIS-N1 fields. Spitzer's increased sensitivity and efficiency in large areal coverage over previous infrared ...

  • The Infrared Array Camera component of the Spitzer Space Telescope Extragalactic First Look Survey 

    Lacy, M.; Wilson, G.; Masci, F.; Storrie-Lombardi, L. J.; Appleton, P. N.; Armus, L.; Chapman, S. C.; Choi, P. I.; Fadda, D.; Fang, F.; Frayer, D. T.; Heinrichsen, I.; Helou, G.; Im, M.; Laine, S.; Marleau, F. R.; Shupe, D. L.; Soifer, B. T.; Squires, G. K.; Surace, J.; Teplitz, H. I.; Yan, L. (2005-11)
    We present Infrared Array Camera (IRAC) data and source catalogs from the Spitzer Space Telescope Extragalactic First Look Survey. The data were taken in four broad bands centered at nominal wavelengths of 3.6, 4.5, 5.8 ...

  • 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 ...

  • Obscured and unobscured active galactic nuclei in the Spitzer Space Telescope First Look Survey 

    Lacy, M.; Storrie-Lombardi, L. J.; Sajina, A.; Appleton, P. N.; Armus, L.; Chapman, S. C.; Choi, P. I.; Fadda, D.; Fang, F.; Frayer, D. T.; Heinrichsen, I.; Helou, G.; Im, M.; Marleau, F. R.; Masci, F.; Shupe, D. L.; Soifer, B. T.; Surace, J.; Teplitz, H. I.; Wilson, G.; Yan, L. (2004-09)
    Selection of active galactic nuclei (AGN) in the infrared allows the discovery of AGN whose optical emission is extinguished by dust. In this paper, we use the Spitzer Space Telescope First Look Survey (FLS) to assess what ...
