摘要:
We present the identification of a bright submillimeter galaxy (SMG) in the field of Abell 2218. The galaxy has a spectroscopic redshift of similar to 4, and is currently the highest redshift SMG known. It is detected at all wavelengths from optical to submm, including the Spitzer IRAC bands. We discuss the properties of this galaxy, which is undergoing intense star formation at a rate similar to 600 M(circle dot)yr(-1). We also compare the properties to those of radio-preselected submm-bright galaxies. The z approximate to 4 result extends the redshift distribution of SMGs.
