The Galactic Arecibo L-Band Feed Array HI (GALFA-HI) Survey is an ongoing survey of neutral hydrogen in the Galaxy. The development of the bulk of the data reduction procedures and software for GALFA-HI and the analysis of certain high-velocity clouds within the survey was the centerpiece of the my thesis.
The survey is conducted via a 'jigsaw puzzle' approach, in which all data are taken with the same spectrometer setup, but individual researchers are allowed to observe specific regions of interest. Using this approach, and also observing commensally with ALFALFA, AGES and GALFACTS, we have observed approximately 50% of the 13,000 square degrees available to the Arecibo 305m telescope at 3.5' resolution with a spectral resolution of 0.18 km/s.
