    Description: The evolution of galaxies is connected to the growth of supermassive black holes in their centers. During the quasar phase, a huge luminosity is released as matter falls onto the black hole, and radiation-driven winds can transfer most of this energy back to the host galaxy. Over five different epochs, we detected the signatures of a nearly spherical stream of highly ionized gas in the broadband x-ray spectra of the luminous quasar PDS 456. This persistent wind is expelled at relativistic speeds from the inner accretion disk, and its wide aperture suggests an effective coupling with the ambient gas. The outflow's kinetic power larger than 10(46) ergs per second is enough to provide the feedback required by models of black hole and host galaxy coevolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nardini, E -- Reeves, J N -- Gofford, J -- Harrison, F A -- Risaliti, G -- Braito, V -- Costa, M T -- Matzeu, G A -- Walton, D J -- Behar, E -- Boggs, S E -- Christensen, F E -- Craig, W W -- Hailey, C J -- Matt, G -- Miller, J M -- O'Brien, P T -- Stern, D -- Turner, T J -- Ward, M J -- New York, N.Y. -- Science. 2015 Feb 20;347(6224):860-3. doi: 10.1126/science.1259202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Astrophysics Group, School of Physical and Geographical Sciences, Keele University, Keele, Staffordshire ST5 5BG, UK. e.nardini@keele.ac.uk. ; Astrophysics Group, School of Physical and Geographical Sciences, Keele University, Keele, Staffordshire ST5 5BG, UK.
