Title: Investigating the properties of interacting void galaxies from the SDSS
Abstract:
Galaxies in the most underdense regions of the universe, the voids,
have quite different evolutionary histories than those in more dense
regions. In particular, the frequency of interactions and their
histories (major and minor mergers) are strongly affected by this low
density environment. A galaxy's merger history determines the growth
rate of its central black hole, which is estimated from the nuclear
emission-line properties. We propose to observe potentially interacting
void galaxies identified from the Sloan Digital Sky Survey (SDSS) in
order to look for merger-induced star-formation and active galactic
nucleus (AGN) activity. The results will help determine the effects of
environment on galaxy evolution and help address the issue of the "void
phenomenon;" the apparent lack of faint galaxies in void regions.
