Title: Identifying AGN-powered Lyman Alpha Emitters
Date: Thursday, March 14th, 2013
Time: 11:30
Venue: Villa Bazzoni

Abstract: The most natural explanation for the large Lya luminosities is associated with star forming activities. Short-lived, massive stars produce large amount of UV photons and H-atoms recombine on a short time scale in the dense interstellar medium emitting Lya photons. Interestingly, a fraction of LAEs seem to host an Active Galactic Nuclei (AGN). I will present our recent work in this talk, radiative transfer cosmological simulations of a prototypical z=6.6 LAE. I will show that this indeed possible and introduce a simple but solid diagnostic tool to unambiguously assess if the LAE luminosity is powered by an AGN or by starburst.
