A constant intrinsic thickness for dwarf irregular galaxies?

Monthly Notices of the Royal Astronomical Society: Letters, 2016
Abstract We assess the intrinsic thickness parameter, qo, for a sample of dwarf irregular galaxies and compare to larger, more massive spiral galaxy systems. We use optical photometry to determine b/a (minor-to-major axial ratio), and we use the H i kinematic inclination angle to derive qo.

Dwarf Irregular Galaxies of the Local Group

2014
Local Group dwarf irregulars (dIrrs) cover an enormous range in star formation properties. Here I discuss these tiny galaxies as probes of star formation at the extremes of low gas densities and low metallicities. We have learned that (1) Star formation is inefficient in dIrrs and yet at very low \(\Sigma_{\rm HI}\) (\(
