	Astronomy Tea Talks at Caltech Mondays, Hameetman auditorium (Cahill) Tea:  4.00pm Talk: 4.15pm
	Organized by: Nick Konidaris (npk@astro.caltech.edu) Joaquin Vieira (vieira[at]astro.caltech.edu)

We find a higher AGN fraction in 70-micron selected galaxies compared to previous studies. This difference may be due to 70-micron galaxies hosting AGNs that are heavily absorbed (Compton-thick). I present evidence that these systems are ideal test-beds for merger scenarios in which gas-rich galaxies merge, go through a deeply-embedded ULIRG phase before emerging as an X-ray and optically identified AGN. I compile galaxies at different evolutionary stages allowing us to witness this process at redshift ~ 0.7. Lastly, I will highlight the potential of future multi-wavelength studies to constrain such evolutionary scenarios.
