A high-dispersion molecular gas component in nearby galaxies

Author: Caldú-Primo, Anahi ; Schruba, Andreas ; Walter, Fabian ; Leroy, Adam ; Sandstrom, Karin ; de Blok, W J G ; Ianjamasimanana, R ; Mogotsi, K M Date: 2013 We present a comprehensive study of the velocity dispersion of the atomic (H I) and molecular (H2) gas components in the disks (R R 25) of a sample of 12 nearby spiral galaxies with moderate inclinations. Our analysis is based on sensitive ... Read more
Accurate Recovery of H i Velocity Dispersion from Radio Interferometers

Author: Ianjamasimanana, R ; Blok, W J G de ; Heald, George H Date: 2017 Gas velocity dispersion measures the amount of disordered motion of a rotating disk. Accurate estimates of this parameter are of the utmost importance because the parameter is directly linked to disk stability and star formation. A global ... Read more
