Massive stars shaping the ISM:Hi holes and shells in nearby galaxies
(1999)
Neutral hydrogen (H I) is a magnificent tool when studying the structure of the interstellar medium (ISM) as it is relatively easily observable and can be mapped at good spatial and velocity resolution with modern instruments. ...
HI Observations of Early-Type Galaxies
(Astronomical Society of the Pacific, 1999)
We present high resolution (15") HI observations of the S0 galaxy NGC 404. We derive an HI mass of MHi = 6.7 x 10???, in good agreement with previous measurements. The HI is distributed in a broad annulus (a doughnut) and ...
HI properties of Low Surface Brightness dwarf and blue compact dwarf galaxies
(Astronomical Society of the Pacific, 1999)
We present high resolution (~15") VLA HI observations of one LSB dwarf galaxy and 5 Blue Compact Dwarfs. Previous works have emphasized the difference in the peak column density of the HI between the two types of galaxy. ...
Panel Discussion: Star Formation in Early-Type Galaxies
(Astronomical Society of the Pacific, 1999)
A panel discussion on past and current star formation in early-type galaxies was held on the second day of the conference. The panelists were Luc Binette, Elias Brinks, Paul Goudfrooij, Lisa Young, George Hau, Rick Pogge ...
Neutral Hydrogen (21 Centimeter) Absorption in Seyfert Galaxies: Evidence for Free-Free Absorption and Subkiloparsec Gaseous Disks
(1999)
Active galaxies are thought to be both fueled and obscured by neutral gas removed from the host galaxy and funneled into a central accretion disk. We performed a VLA imaging survey of 21 cm absorption in Seyfert and starburst ...
Interaction Between NGC 5394 and NGC 5395
(Astronomical Society of the Pacific, 1999)
The spiral galaxies NGC 5394/95 (at a distance of 47 Mpc) are involved in a recent, close, nonmerging encounter. The smaller galaxy, NGC 5394, has two long, fairly symmetric, open tidal arms (see Figure 1); in numerical ...
Holes and shells in the interstellar medium of the nearby dwarf galaxy IC 2574
(1999)
We present H I synthesis observations of the nearby dwarf galaxy IC 2574 (a member of the M81 group of galaxies) made with the NRAO2 Very Large Array (VLA) in its B, C, and D conÐgurations at high spatial and velocity ...
Ocular Galaxies: NGC 2535 and its Starburst Companion NGC 2536
(The International Astronomical Union, 1999)
VLA HI imaging of the Low Surface Brightness dwarf galaxy DDO47
(Astronomical Society of the Pacific, 1999)
We present high resolution VLA-observations of the nearby Low Surface Brightness Galaxy DDO 47. This object shows many hole-like structures in its neutral interstellar medium. The majority of the detected H I-shells are ...
