An HI Rogues Gallery
J. E. Hibbard, J. H. van Gorkom, M. P. Rupen +1
We have begun a compilation of HI maps of peculiar galaxies kindly contributed by individual investigators, many as part of the ``Gas & Galaxy Evolution'' conference. In this galle…
HST Observations of the Nuclear Regions of the Toomre Sequence of Merging Galaxies
S. Laine, R. P. van der Marel, T. Boeker +3
We present first results from an HST WFPC2 imaging and STIS spectroscopy program to investigate the structural and star forming properties in the nuclear regions of the Toomre Sequ…
From Globular Clusters to Tidal Dwarfs: Structure Formation in Tidal Tails
Jane Charlton, Karen Knierman, Sally Hunsberger +4
Star clusters can be found in galaxy mergers, not only in central regions, but also in the tidal debris. In both the Eastern and Western tidal tails of NGC 3256 there are dozens of…
HI in Early-Type Galaxies
T. Oosterloo, R. Morganti, E. M. Sadler
We briefly discuss the main differences between the HI properties of luminous and low-luminosity early-type galaxies. In luminous early-type galaxies the HI is often irregularly di…
Mergers of Galaxies from an HI Perspective
J. E. Hibbard
HI spectral line mapping studies are a unique probe of morphologically peculiar systems. Not only does HI imaging often reveal peculiarities that are totally unsuspected at optical…
Molecular Gas in Optically Selected Mergers
Min S. Yun, J. E. Hibbard
We have mapped the 2.6 mm CO (1-0) emission in three optically selected "Toomre Sequence" mergers (NGC 520, NGC 3921, NGC 4676). The molecular gas distribution is well resolved by…
