Abstract:
We revisit the HI size-mass (DHII-MHI) relation of galaxies with a
sample of more than 500 nearby galaxies covering over five orders of
magnitude in HI mass and more than 10 B-band magnitudes. The relation
is remarkably tight with a scatter σ∼0.06dex, or 14 per cent.
The scatter does not change as a function of galaxy luminosity, HI
richness or morphological type. The relation is linked to the fact
that dwarf and spiral galaxies have a homogeneous radial profile of HI
surface density in the outer regions when the radius is normalized by
DHI. The early-type disc galaxies typically have shallower HI radial
profiles, indicating a different gas accretion history. We argue that
the process of atomic-to-molecular gas conversion or star formation
cannot explain the tightness of the DHI-MHI relation. This simple
relation puts strong constraints on simulation models for galaxy
formation.
Description:
We have compiled HI interferometric data from 15 projects.
Only galaxies with reliable DHI measurements are considered.
