S. Stanimirovic (RAL/UC Berkeley), GALFA Consortium
The Arecibo L-band Feed Array (ALFA) will enable numerous large scale HI surveys which will serve as a standard reference for many years to come and will have an enormous impact on the field of Galactic astronomy. The science case for the consortium for Galactic studies with ALFA (GALFA) is rich and diverse and covers an impressive range of scientific questions, from formation mechanisms of molecular clouds, through the disk-Halo connection and origin of high velocity clouds, to statistical analyses of large HI maps to characterize interstellar turbulence. While individual GALFA projects focus on particular parts of the sky, all individual surveys will be pieced together at the end, just like a `jigsaw-puzzle', to culminate in the HI survey of the whole Galactic sky visible from Arecibo. In this talk I will highlight the basic powers of ALFA for HI spectral-line surveys and summarize several proposed surveys, their major scientific goals and observing parameters.
The Arecibo Observatory is part of the National Astronomy and Ionosphere Center, operated by Cornell University under a cooperative agreement with the National Science Foundation.
