Non-confirmation of reported HI clouds without optical counterparts in the Hercules Cluster
W. van Driel, K. O'Neil, V. Cayatte +8
21 cm HI line observations were made with the Arecibo Gregorian telescope of 9 HI clouds in the Hercules Cluster which were reported as tenative detections in a VLA HI study of the…
Deriving the redshift of distant galaxies with Gamma-Ray Burst transient edges
E. Le Floc'h, P. -A. Duc, I. F. Mirabel
Cosmological Gamma-Ray Bursts (GRBs) offer a unique perspective to probe the evolution of distant galaxies. We discuss one of the multiple benefits of this approach, i.e. the detec…
Tidal Dwarf Candidates in a Sample of Interacting Galaxies. II. Properties and Kinematics of the Ionized Gas
P. M. Weilbacher, P. -A. Duc, U. Fritze-v. Alvensleben
We present low-resolution spectroscopy of the ionized gas in a sample of optical knots located along the tidal features of 14 interacting galaxies and previously selected as candid…
Large Velocity Gradients in the Tidal Tails of the Interacting Galaxy AM 1353-272 ("The Dentist's Chair")
Peter M. Weilbacher, Uta Fritze-v. Alvensleben, Pierre-Alain Duc +1
We present VLT observations of the interacting system AM 1353-272. Using the FORS2 instrument, we studied the kinematics of the ionized gas along its prominent tidal tails and disc…
Molecular gas in the intergalactic medium of Stephan's Quintet
Ute Lisenfeld, Stephane Leon, Jonathan Braine +3
Stephan's Quintet (SQ) is a Hickson Compact Group well known for its complex dynamical and star formation history and its rich intergalactic medium (IGM). In order to study the ext…
