| 英文摘要 | Abstract We construct a SCUBA-2 450 μm map in the COSMOS field that covers an area of 300 arcmin2 and reaches a 1σ noise level of 0.65 mJy in the deepest region. We extract 256 sources detected at 450 μm with signal-to-noise ratios?>4.0 and analyze the physical properties of their multiwavelength counterparts. We find that most of the sources are at z???3, with a median of . About of our sources are classified as starburst galaxies based on their total star formation rates (SFRs) and stellar masses (M*). By fitting the far-infrared spectral energy distributions, we find that our 450 μm selected sample has a wide range of dust temperatures (20 K ? Td ? 60 K), with a median of K. We do not find a redshift evolution in dust temperature for sources with at z? |
