SMA observations on faint Submillimeter Galaxies with S < 2 mJy: Ultra Dusty Low-Luminosity Galaxies at High Redshift
Chian-Chou Chen, Lennox L. Cowie, Amy J. Barger +2
We obtained SMA observations of eight faint (intrinsic 850 m fluxes 2 mJy) submillimeter galaxies (SMGs) discovered in SCUBA images of the massive lensing cluster fields A37…
Resolving the Cosmic Far-Infrared Background at 450 and 850 Microns with SCUBA-2
Chian-Chou Chen, Lennox L. Cowie, Amy J. Barger +5
We use the SCUBA-2 submillimeter camera mounted on the JCMT to obtain extremely deep number counts at 450 and 850um. We combine data on two cluster lensing fields, A1689 and A370,…
Characterisation of SCUBA-2 450um and 850um-selected Galaxies in the COSMOS Field
Caitlin M. Casey, Chian-Chou Chen, Lennox Cowie +8
We present deep 450um and 850um observations of a large, uniformly covered 394arcmin^2 area in the COSMOS field obtained with the SCUBA-2 instrument on the James Clerk Maxwell Tele…
Faint Submillimter Galaxy Counts at 450 micron
Chian-Chou Chen, Lennox L. Cowie, Amy J. Barger +5
We present the results of SCUBA2 observations at 450 micron and 850 micron of the field lensed by the massive cluster A370. With a total survey area > 100 arcmin2 and 1 sigma sensi…
Precise Identifications of Submillimeter Galaxies: Measuring the History of Massive Star-Forming Galaxies to z>5
A. J. Barger, W. -H. Wang, L. L. Cowie +3
We carried out extremely sensitive Submillimeter Array (SMA) 340 GHz (860 micron) continuum imaging of a complete sample of SCUBA 850 micron sources (>4 sigma) with fluxes >3 mJy i…
Faint Submillimeter Galaxies behind the Massive Lensing Cluster A2390
Chian-Chou Chen, Lennox L. Cowie
Current studies on Submillimeter Galaxies (SMGs) mostly focus on bright sources with 850 micron flux greater than 2 mJy, and the results have shown that they are likely high redshi…
Submillimeter sources behind the massive lensing clusters A370 and A2390
Chian-Chou Chen, Lennox L. Cowie, Wei-Hao Wang +2
We report 850 micron Submillimeter Array (SMA) observations of four gravitationally lensed submillimeter galaxies (SMGs), A370-2, A2390-1, A2390-3 and A2390-4, which were originall…
