  • 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 ...

  • Sub-mm and near-IR observations of galaxies selected at 170 microns 

    Sajina, A.; Borys, C.; Chapman, S.; Dole, H.; Halpern, M.; Lagache, G.; Puget, J. -L; Scott, D. (2003-08-21)
    We present results from JCMT sub-mm observations of sources selected from the {\sl ISO} FIRBACK (Far-IR BACKground) survey, along with UKIRT near-IR imaging of a sub-sample. This gives valuable insight into the brightest ...
