Using HI stacking to study galaxy properties in the nearby universe (Looking for needles in the HI-stack)
Neutral atomic hydrogen (Hi) is the raw fuel from which the star-forming molecular gas forms and is therefore an important tracer of galaxy evolution. Due to the intrinsic faintness of the Hi emission line (observed at rest at 21 cm), galaxies beyond a few hundred megaparsecs are difficult to observ...
