2004 Symposium - International astronomical union  
We discuss our ongoing multi-instrument HST investigation of the nuclear regions of the 11 interacting and merging galaxies in the Toomre Sequence. We are studying the nuclear kinematics using STIS (G750M) spectra, the nuclear stellar populations using STIS (G430L) spectra, and the nuclear morphology using NICMOS and WFPC2 images. The results will provide new insight into the physical processes that operate during galaxy interactions.
