Gas without Stars in the Locak Group, and other Discoveries with the Green Bank Telescope
Very deep 21cm HI observations with the Green Bank
Telescope (GBT) have uncovered a group of clouds that lie between the
galaxies M31 and M33but do not appear to be directly connected to
either system and do not appear to contain stars. These are the most
recent (and most puzzling) of a population of large gas clouds that are
common around the galaxies of the Local Group. I'll discuss the
properties and possible origins of this material and its implication
for the evolution of M31 and the Milky Way. In addition, I'll give a
brief discussion of the recent detection of neutral clouds in the wind
from the Galactic Center, and review of some recent discoveries made
with the GBT.
