The Bluedisk survey: thickness of HI layers in gas rich spiral galaxies
Toky H. Randriamampandry, Jing Wang, K. Moses Mogotsi
We use an empirical relation to measure the HI scale height of relatively HI rich galaxies using 21-cm observations. The galaxies were selected from the BLUEDISK, THINGS and VIVA s…

Angular momentum and local gravitational instability in galaxy discs: does correlate with or ?
Alessandro B. Romeo, Keoikantse Moses Mogotsi
We introduce a new diagnostic for exploring the link between angular momentum and local gravitational instability in galaxy discs. Our diagnostic incorporates the latest developmen…

The stellar velocity dispersion in nearby spirals: radial profiles and correlations
Keoikantse Moses Mogotsi, Alessandro B. Romeo
The stellar velocity dispersion, , is a quantity of crucial importance for spiral galaxies, where it enters fundamental dynamical processes such as gravitational instability and…
