Dwarf spheroidal galaxies of the Local Group are close satellites of the Milky Way characterized by a large mass-to-light ratio and are not expected to be the site of non-thermal h…
The origin of ultra-fast outflows in AGN: Monte-Carlo simulations of the wind in PDS 456
Kouichi Hagino, Hirokazu Odaka, Chris Done +4
Ultra-fast outflows (UFOs) are seen in many AGN, giving a possible mode for AGN feedback onto the host galaxy. However, the mechanism(s) for the launch and acceleration of these ou…
