QSO MUSEUM III: the circumgalactic medium in Ly emission around 120 quasars covering the SDSS parameter space. Witnessing the instantaneous AGN feedback on halo scales
Jay González Lobos, Fabrizio Arrigoni Battaia, Aura Obreja +3
Recent surveys show that quasars are surrounded by Hydrogen Lyman- (Ly) glows with diverse emission levels and extents. These seem to depend on the activity of embedded…
