Title: Virgo, a Laboratory for Studying Environmentally Driven Galaxy Evolution

Aeree Chung (Smithsonian Astrophysical Observatory)

Abstract:

As the nearest rich yet dynamically young galaxy cluster, Virgo is an
ideal place to study great details of how galaxies get modified
through interactions with their surroundings (e.g. ISM stripping due
to intra cluster medium and tidal interactions with other galaxies or
the cluster potential). In this talk, I will present real examples of
Virgo cluster galaxies undergoing different environmental effects
found in our recent VLA HI imaging study, VIVA (VLA Imaging of Virgo
galaxies in Atomic gas). I will discuss 1) which processes are
dominant in different density regions, 2) how far out the impact of
the cluster reaches, and 3) how the environment, in particular by
removing the ISM from the galactic disk, will affect galaxy morphology
and color.
