Aperture Synthesis Spectral Line Imaging: Exploring the Third Dimension (Invited Talk)
(Astronomical Society of the Pacific, 2002)
Radio astronomers are in a privileged position as compared to optical and near-IR observers because almost from the beginning of radioastronomical observations it proved possible to obtain spectral information at velocity ...
On-Going Galaxy Formation
(2002)
H I and CO Emission in Blue Compact Dwarfs: Haro 2 and Haro 4/26
(Astronomical Society of the Pacific, 2002)
We present VLA HI imaging of two actively star-forming dwarf galaxies, Haro 2 and Haro 4, and of the spiral galaxy NGC 3510 (Haro 26), some 22' SW of Haro 4 (8.5kpc). We also present a map of the CO(1-0) distribution of ...
Bloated Dwarfs: The Thickness of the HI Disks in Irregular Galaxies
(Astronomical Society of the Pacific, 2002)
Somewhat counterintuitively, the gas disks of (dwarf) irregular galaxies, such as the LMC, are thicker than those of normal disk galaxies, both in relative as well as in absolute terms. In retrospect, this is easily ...
Star Formation in Tidal Dwarf Galaxies
(Astronomical Society of the Pacific, 2002)
Tidal Dwarf Galaxies (TDGs) are objects presently forming from gas that has been expelled from their parent galaxies during an interaction. We searched for CO emission in a sample of 11 TDGs, of which 8 were detected. The ...
Abundant molecular gas in tidal dwarf galaxies: On-going galaxy formation
(2001-10)
We investigate the process of galaxy formation as can be observed in the only currently forming galaxies { the so-called Tidal Dwarf Galaxies, hereafter TDGs { through observations of the molecular gas detected via its CO ...
