Structure and Kinematics of the Nearby Dwarf Galaxy UGCA 105
Philip Schmidt, Gyula Jozsa, Gianfranco Gentile +5
Owing to their shallow stellar potential, dwarf galaxies possess thick gas disks, which makes them good candidates for studies of the galactic vertical kinematical structure. We pr…
Star Formation in Two Luminous Spiral Galaxies
Deidre A. Hunter, Bruce G. Elmegreen, Vera C. Rubin +4
We have examined star formation in two very luminous (M_V=-22 to -23) Sc-type spiral galaxies, NGC 801 and UGC 2885, using ultra-deep Halpha images. We combine these with UBV and 2…
HI in HO: Hoag's object revisited
Noah Brosch, Ido Finkelman, Tom Oosterloo +2
We present new HI observations of Hoag's Object obtained with the Westerbork Synthesis Radio Telescope (WSRT). The data show that the luminous optical ring around the elliptical bo…
HALOGAS observations of NGC 5023 and UGC 2082: Modeling of non-cylindrically symmetric gas distributions in edge-on galaxies
P. Kamphuis, R. J. Rand, G. I. G. Józsa +7
In recent years it has become clear that the vertical structure of disk galaxies is a key ingredient for understanding galaxy evolution. In particular, the presence and structure o…
HALOGAS: Extraplanar gas in NGC 3198
G. Gentile, G. I. G. Jozsa, P. Serra +6
We present the analysis of new, deep HI observations of the spiral galaxy NGC 3198, as part of the HALOGAS (Westerbork Hydrogen Accretion in LOcal GAlaxieS) survey, with the main a…
The Bluedisks project, a study of unusually HI-rich galaxies: I. HI Sizes and Morphology
Jing Wang, Guinevere Kauffmann, Gyula I. G. Józsa +10
We introduce the "Bluedisk" project, a large program at the Westerbork Synthesis Radio Telescope (WSRT) that has mapped the HI in a sample of 23 nearby galaxies with unusually high…
