HII regions feeding the interstellar medium in M83
Javier Blasco-Herrera, Kambiz Fathi, John Beckman +5
We analyse the internal dynamics of star-forming HII regions and their efficiency in interacting with the ISM. We use GHaFaS (Fabry-Perot) data of the nearby spiral galaxy M83 to p…
Pattern Speeds of Bars and Spiral Arms From H-alpha Velocity Fields
Kambiz Fathi, John Beckman, Nuria Piñol-Ferrer +3
We have applied the Tremaine-Weinberg method to 10 late-type barred spiral galaxies using data cubes, in H-alpha emission, from the GHAFAS and FANTOMM Fabry-Perot spectrometers. We…
A slow bar in a dark matter dominated galaxy
Laurent Chemin, Olivier Hernandez
We report on an estimate of the bar pattern speed Omega_p for the low surface brightness spiral galaxy UGC 628. We applied the Tremaine-Weinberg method to high resolution Halpha ve…
