First Constraints on Source Counts at 350 μm.
Astrophysical Journal, 665
We have imaged a 6 arcmin2 region in the Boötes Deep Field using the 350 m–optimized second-generation Submillimeter High Angular Resolution Camera (SHARC II), achieving a peak 1 sensitivity of 5 mJy. We detect three sources above 3 , and determine a spurious source detection rate of 1.09 in our maps. In the absence of 5 detections, we rely on deep 24 m and 20 cm imaging to deduce which sources are most likely to be genuine, giving two real sources. From this we derive an integral source count of 0.84 sources arcmin-2 at S > 13 mJy, which is consistent with 350 m source count models that have an IR-luminous galaxy population evolving with redshift. We use these constraints to consider the future for ground-based short-submillimeter surveys.
