Breaking news about G2, GRBs against life in the universe, Ulisses visit

We discussed the new, potentially breaking news observations, on the G2 object on its way to the supermassive black hole in Sgr A*. As it turns out, it is probably a star (see its stellar PSF) that will probably not be tidally disrupted. Much less exciting that what everybody was expecting.

Our visitor this week, Ulisses Barres de Almeida, told us about the Top 3 scientific highlights of the Cherenkov Telescope Array (CTA) for AGNs in his opinion: the characterization of the extragalactic background light, dark matter and breaking the degeneracy between hadronic vs leptonic scenarios for the gamma-ray origin of the emission from AGN jets.
