The disc-averaged star formation relation for Local Volume dwarf galaxies

Lopez-Sanchez, A R; Lagos, Claudia; Young, Tye; Jerjen, Helmut


Spatially resolved HI studies of dwarf galaxies have provided a wealth of precision data. However these high-quality, resolved observations are only possible for handful of dwarf galaxies in the Local Volume. Future HI surveys are unlikely to improve the current situation. We therefore explore a method for estimating the surface density of the atomic gas from global HI parameters that are conversely widely available. We perform empirical tests using galaxies with resolvedHI maps, and find that...[Show more]
