Quantifying Resonant Structure in NGC 6946 from Two-dimensional Kinematics
Kambiz Fathi, Silvia Toonen, Jesús Falcón-Barroso +5
We study the two-dimensional kinematics of the H-alpha-emitting gas in the nearby barred Scd galaxy, NGC 6946, in order to determine the pattern speed of the primary m=2 perturbati…
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…
