Induced Activity in Mixed-Morphology Galaxy Pairs
Results from a spectroscopic study of the nuclear emission of a sample of 97 spirals in isolated galaxy pairswith mixed morphology (E+S) are presented and discussed. The Main results of this study are: (1) AGNactivity is found in 40% of the spiral galaxies in these pairs, (2) Only one out of the 39...

| Summary: | Results from a spectroscopic study of the nuclear emission of a sample of 97 spirals in isolated galaxy pairswith mixed morphology (E+S) are presented and discussed. The Main results of this study are: (1) AGNactivity is found in 40% of the spiral galaxies in these pairs, (2) Only one out of the 39 AGN found shows type 1 activity, and (3) AGN tend to have closer companions than star forming galaxies. These results are atodds with a simple Unified Model for Seyferts, where only obscuration/orientation effects are of relevance, and neatly support an evolutionary scenario where interactions trigger nuclear activity. |
