Abundant molecular gas in the intergalactic medium of Stephan's Quintet
(2002-11)
Stephan's Quintet (SQ) is a system consisting of at least four interacting galaxies which is well known for its complex dynamical and star formation history. It possesses a rich intergalactic medium (IGM), where hydrogen ...
HI Observations of Isolated Triple Galaxies.
(Astronomical Society of the Pacific, 2002)
We present preliminary results from Effelsberg 100-m HI observations of a sample of 27 Triple Galaxies selected from the Karachentseva Catalogue of Isolated Triplets. These observations were complemented with optical CCD ...
Damped Lyman-alpha Absorption from the Nearby Low Surface Brightness Galaxy SBS 1543+593: a Summary
(Astronomical Society of the Pacific, 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 ...

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 ...
