		| Abstract: | 
		In this contribution, I will review the latest results of our ongoing
 work to study the central gas flows in merging galaxies, focusing on
 triggered star formation, presence of an AGN and changes in the
 gas-phase metallicity.  Results from a sample of close galaxy pairs are
 compared with bar driven gas inflows in order to quantify the relative
 importance of hierarchical versus secular processes. |
