Optimizing spectral stacking for 21-cm observations of galaxies: accuracy assessment and symmetrized stacking
Francesco Sinigaglia, Ed Elson, Giulia Rodighiero +1
We present an assessment of the accuracy of common operations performed in -cm spectral line stacking experiments. To this end, we generate mock interferometric data surveying…
Choirs, HI Galaxy Groups: Catalogue and Detection of Star-forming Dwarf Group Members
Sarah M. Sweet, Gerhardt Meurer, Michael J. Drinkwater +24
Hα observations centred on galaxies selected from the HI Parkes All Sky Survey (HIPASS, Barnes et al. 2001) typically show one and sometimes two star-forming galaxies within the ap…
HI synthesis observations of the blue compact dwarf NGC 1705
E. C. Elson, W. J. G. de Blok, R. C. Kraan-Korteweg
Australia Telescope Compact Array HI-line observations of the nearby dwarf galaxy NGC 1705 are presented. The data are used to trace the gravitational potential of the galaxy out t…
The Distribution of Mass in the Orion Dwarf Galaxy
Noemi Frusciante, Paolo Salucci, Daniele Vernieri +2
Dwarf galaxies are good candidates to investigate the nature of Dark Matter, because their kinematics are dominated by this component down to small galactocentric radii. We present…
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…
