22 Aug 2001 | Subject: | astro-ph | Affiliation: | Imperial College), B. Mobasher (STScI), B. Chan (University of Sydney) and L. Cram (University of Sydney | Abstract: | In the course of the follow-up multiwavelength study of a deep radio survey we have discovered that the milli-Jansky radio source PDFJ011423 is a low-redshift (z = 0.65) extremely red galaxy (ERG) with K=15.3, R-K = 5.8 and J-K = 3.1. Optical, infrared and radio photometry, together with optical and near-infrared spectroscopy, reveal a heavily obscured galaxy (A_V=5-6, from the observed Balmer decrement) undergoing vigorous star formation and presenting an active galactic nucleus (AGN). PDFJ011423 is a representative member of the dusty ERG population, providing a local counterpart for studying more distant ERGs. | Source: | arXiv, astro-ph/0108361 | Services: | Forum | Review | PDF | Favorites |
