The MEGA (Meetings ExtraGalactic of Arcetri) is a series of informal seminars about extragalactic topics held at INAF Arcetri, mostly on Wednesdays.

Indeed they are more informal than the official Arcetri Seminars series, participants are welcome to interrupt with comments and questions, and speakers are invited to talk about on-going work, in order to get constructive comments and to foster local collaborations.

To propose a MEGA, please contact any of the staff member listed in the page of the Galaxies, AGN, and Cosmology group.
