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 ...
On-Going Galaxy Formation

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 ...
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 ...
