| Abstract: |
To provide observations of what happens as two galaxies interact, we have started an observational program to study how the ISM and star formation vary along a merging sequence of interacting luminous IR galaxies. We use BIMA maps of the CO(1-0) emission, VLA HI and radio continuum observations, ISOCAM 7 and 15 micron images, optical and near-IR imaging to characterize the gas distribution and star formation activities. Preliminary results of this survey are described, as well as detailed results on the active star forming ``interaction" region in the Antennae (Arp 244). Finally, 15% of a complete sample of ULIG are found to consist of two galaxies separated by 10 to 60 kpc, in apparent conflict with the conventional view that ULIG are the final stages of the merging of two galaxies. |
