Abstract

The Arecibo Galaxy Environment Survey (AGES) is carrying out blind H I surveys of a number of different environments in the local Universe in order to determine what effect this has on the H I content and morphology. Whe complete, it will cover 200 square degrees in 13 regions, spanning the whole gamut of galaxy environments from the Local Void through to the Virgo Cluster. Results so far indicate that the faint‐end slope of the H I Mass Function (HIMF) is strongly influenced by the environment; far fewer small galaxier, relative to the number of large galaxies, are found in less dense environments. However, so far only a small number of fields have been analysed, not including the densest and least‐dense environments.
