Oral title: The Incidence of Buried Dual AGN in Advanced Mergers: New results from Chandra

Oral abstract: Interactions between galaxies are predicted to cause gas inflows that can trigger nuclear activity. Since 
inflowing material can obscure the nuclei of the galaxies, previous optical studies could be insensitive to obscured active 
galactic nuclei (AGNs) at various stages along the merger sequence. In this talk I summarize recent results of our mid-IR 
and X-ray investigation of advanced mergers which reveal a population of optically invisible single and dual AGNs. These 
observations add to the growing evidence that the epoch of peak black hole growth in mergers occurs in a highly 
obscured phase.
