Rest-Frame MIR Detection of an Extremely Luminous Lyman Break Galaxy with the Spitzer IRS

Astrophysics 2009-11-10 v1

Abstract

We present the first rest-frame ~4 micron detection of a Lyman break galaxy. The data were obtained using the 16 micron imaging capability of the Spitzer Infrared Spectrograph. The target object, J134026.44+634433.2, is an extremely luminous Lyman break galaxy at z=2.79 first identified in Sloan Digital Sky Survey spectra (Bentz, Osmer, & Weinberg 2004). The source is strongly detected with a flux of 0.94 +/- 0.02 mJy. Combining Spitzer and SDSS photometry with supporting ground-based J- and K-band data, we show that the spectral energy distribution is consistent with an actively star-forming galaxy. We also detect other objects in the Spitzer field of view, including a very red MIR source. We find no evidence of a strong lens amongst the MIR sources.
