An Overview of the MHONGOOSE Survey: Observing Nearby Galaxies with MeerKAT
W. J. G. de Blok, E. A. K. Adams, P. Amram +65
MHONGOOSE is a deep survey of the neutral hydrogen distribution in a representative sample of 30 nearby disk and dwarf galaxies with HI masses from 10^6 to ~10^{11} M_sun, and lumi…
The Opacity of Spiral Galaxy Disks IX; Dust and Gas Surface Densities
B. W. Holwerda, R. J. Allen, W. J. G. de Blok +4
Our aim is to explore the relation between gas, atomic and molecular, and dust in spiral galaxies. Gas surface densities are from atomic hydrogen and CO line emission maps. To esti…
An Extreme Pulsar Tail Protruding from the Frying Pan Supernova Remnant
C. -Y. Ng, N. Bucciantini, B. M. Gaensler +3
The Frying Pan (G315.9-0.0) is a radio supernova remnant with a peculiar linear feature (G315.78-0.23) extending 10' radially outward from the rim of the shell. We present radio im…
Quantified HI Morphology III: Merger Visibility Times from HI in Galaxy Simulations
B. W. Holwerda, N. Pirzkal, T. J. Cox +5
Major mergers of disk galaxies are thought to be a substantial driver in galaxy evolution. To trace the fraction and the rate galaxies are in mergers over cosmic times, several obs…
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…
