| dc.description | Recent observational literature suggests that only a small number of colliding galaxies show substantial star formation enhancements before merging. Most have SFRs comparable to those of late-type field galaxies. Preliminary Spitzer studies (with data from the Spirals, Bridges and Tails and SINGs projects) generally confirm this, though with some caveats. If star formation in isolated disks is self-regulated, while collisions disequilibrate much of the disk, then the similarity to star-formation in isolated disks is surprising. Comparisons of observations and dynamical models suggest some resolutions to this paradox, including the role of downsizing. The interesting example of the Arp 82 system is presented. | |
