摘要: Determination of the epoch dependent star-formation rate field galaxies is one principal goals modern observational cosmology. Recently, Hughes et al. (1998) using SCUBA instrument on James Clerk Maxwell Telescope, report detection a new population heavily dust enshrouded, star-forming at high redshifts (z > 2), dramatically altering picture galaxy evolution. However, we show that this interpretation must be treated with caution because ambiguities in identification host galaxies. Based our deep, resolution 1.4 GHz obervations Hubble Deep Field, suggest alternate identifications to sub-mm detections. These argue for substantially lower redshift consequential lowering z 2 sub-mm/far infrared luminosity density and global rate.
