Quantified HI Morphology IV: The Merger Fraction and Rate in WHISP
B. W. Holwerda, N. Pirzkal, W. J. G. de Blok +3
The morphology of the atomic hydrogen (HI) disk of a spiral galaxy is the first component to be disturbed by a gravitational interaction such as a merger between two galaxies. We u…
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…
