| Abstract: | The first part of this talk will be a review of recent research done by the Green Bank Telescope, including studies of the Lunar surface, the cores of infrared-dark clouds, and gas in galaxy clusters. The remainder of the talk will focus on studies of neutral gas outside of the disks of galaxies in the Local Group. At HI column density limits log(NH)~18 there are extensive regions of neutral gas associated with the spiral galaxies in the form of high-velocity clouds,remnants of interaction like the Magellanic Stream, and the material found between M31 and M33. I will present new GBT results on a high-velocity cloud which may be imbedded in a dark matter halo, and on the starless clouds between M31 and M33 whose origin is unknown. | |
