Star Formation Models for the Dwarf Galaxies NGC 2915 and NGC 1705
E C Elson, W J G de Blok, R C Kraan-Korteweg
Crucial to a quantitative understanding of galaxy evolution are the properties of the inter-stellar medium that regulate galactic-scale star formation activity. We present here the…
Quantified HI Morphology II : Lopsidedness and Interaction in WHISP Column Density Maps
B. W. Holwerda, N. Pirzkal, W. J. G. de Blok +4
Lopsidedness of the gaseous disk of spiral galaxies is a common phenomenon in disk morphology, profile and kinematics. Simultaneously, the asymmetry of a galaxy's stellar disk, in…
Quantified HI Morphology I: Multi-Wavelengths Analysis of the THINGS Galaxies
B. W. Holwerda, N. Pirzkal, W. J. G. de Blok +4
Galaxy evolution is driven to a large extent by interactions and mergers with other galaxies and the gas in galaxies is extremely sensitive to the interactions. One method to measu…
Three-dimensional modeling of the HI kinematics of NGC 2915
E. C. Elson, W. J. G. de Blok, R. C. Kraan-Korteweg
The nearby blue compact dwarf, NGC 2915, has its stellar disc embedded in a large, extended (~ 22 B-band scale-lengths) HI disc. New high-resolution HI synthesis observations of NG…
