| Abstract: |
We present a progress report on an ongoing Hα imaging survey of nearby clusters of galaxies. Four clusters have been surveyed to date: A 1367, A 1656, A 347 and A 569. A preliminary comparison of Hα luminosity functions obtained from our imaging survey with those from the prism survey reveals a significant level of incompleteness in the latter. This in turn is due to a combination of insensitivity to low-luminosity emission-line galaxies and to brighter galaxies with weak extended Hα emission. The survey has also revealed a unique population of clustered dwarf emission-line objects which may be the results of recent tidal encounters between larger gas-rich galaxies. |
