SPITZER PHOTOMETRY OF WISE -SELECTED BROWN DWARF AND HYPER-LUMINOUS INFRARED GALAXY CANDIDATES

We present Spitzer 3.6 and 4.5 mu m photometry and positions for a sample of 1510 brown dwarf candidates identified by the Wide-field Infrared Survey Explorer (WISE) all-sky survey. Of these, 166 have been spectroscopically classified as objects with spectral types M(1), L(7), T(146), and Y(12). We present a catalog of Spitzer photometry for all astrophysical sources identified in these fields and use this catalog to identify seven fainter (4.5 mu m ~ 17.0 mag) brown dwarf candidates, which are possibly wide-field companions to the original WISE sources. To test this hypothesis, we use a sample of 919 Spitzer observations around WISE-selected high-redshift hyper-luminous infrared galaxy candidates. For this control sample, we find another six brown dwarf candidates, suggesting that the seven companion candidates are not physically associated. As an adjunct to this paper, we make available a source catalog of ~7.33 x 10 super(5) objects detected in all of these Spitzer follow-up fields for use by the astronomical community.
