Spiral inflow feeding the nuclear starburst in M83, observed in H-alpha emission with the GHAFAS Fabry-Perot interferometer
Kambiz Fathi, John E. Beckman, Andreas A. Lundgren +8
We present observations of the nearby barred starburst galaxy, M83 (NGC5236), with the new Fabry-Perot interferometer GHAFAS mounted on the 4.2 meter William Herschel Telescope on…
On the metallicity dependence of the 24micron luminosity as a star formation tracer
M. Relano, U. Lisenfeld, P. G. Perez-Gonzalez +2
We investigate the use of the rest-frame 24microns luminosity as an indicator of the star formation rate (SFR) in galaxies with different metallicities by comparing it to the (exti…
An Evolutionary Sequence of Expanding Hydrogen Shells in Galaxy Discs
M. Relano, J. E. Beckman, O. Daigle +1
Large HI shells, with diameters of hundreds of pc and expansion velocities of 10-20kms-1 are well observed features of local gas rich galaxies. These shells could well be predicted…
Evolution of Structure in Late-type Spiral Galaxies I: Ionized Gas Kinematics in NGC 628
Kambiz Fathi, John E. Beckman, Almudena Zurita +5
We study two dimensional Fabry-Perot interferometric observations of the nearby face-on late-type spiral galaxy, NGC 628, in order to analyse the ionized gas component of the inter…
Structure and evolution of star-forming gas in late-type spiral galaxies
Kambiz Fathi, John E. Beckman, Almudena Zurita +7
We study two dimensional Fabry-Perot interferometric observations of the nearby face-on late-type spiral galaxy, NGC 628. We investigate the role of the individual HII regions toge…
