Hunting for dark galaxies with FAST
Large scale neutral hydrogen (HI) survey of the local universe is one of the major science drive for the Five-hundred Meter Aperture Spherical radio Telescope (FAST) project. As pointed out by Prof. Rendong Nan, the founder and the late Chief Scientist & Chief Engineer of the FAST project, the FAST HI survey can address many important astrophysical questions, such as investigating the extent of HI disks; studying the extended rotation curve to unprecedented distance; mapping out the distribution of dark matter in the local group; searching for low mass galaxies in void regions; and detecting Cold Dark Matter Satellites and possible HI companions.
