20 Oct 1998 | | Subject: | astro-ph | | Affiliation: | University of New South Wales, University of Bristol, IGPP, Lawrence Livermore National Laboratory, Anglo-Australian Observatory, University of Wales, Cardiff, University of Sydney | | Abstract: | We are using the 2dF spectrograph to make a survey of all objects (`stars’ and `galaxies’) in a 12 sq.deg region towards the Fornax cluster. We have discovered a population of compact emission-line galaxies unresolved on photographic sky survey plates and therefore missing in most galaxy surveys based on such material. These galaxies are as luminous as normal field galaxies. Using H-alpha to estimate star formation they contribute at least an additional 5 per cent to the local star formation rate. | | Source: | arXiv, astro-ph/9810294 | | Services: | Forum | Review | PDF | Favorites | |
