- Can Ionized Outflows in AGN Produce Important Feedback Effects? The Case of NGC 4051 Smita Mathur Fabrizio Nicastro Martin Elvis Elena Jiménez-Bailón Yair Krongold Nancy Brickhouse Luc Binette Física, Astronomía y Matemáticas rays: galaxies galaxies: active galaxies: Seyfert Galaxies: absorption lines Using a 100 ks XMM-Newton exposure of the Narrow Line Seyfert 1 NGC 4051, we show that the time evolution of the ionization state of the X-ray absorbers in response to the rapid and highly variable X-ray continuum constrains all the main physical and geometrical properties of an AGN Warm Absorber wind. An accretion disk origin for the warm absorber wind is strongly suggested. A radial flow in a spherical geometry is unlikely, and a conical wind geometry is preferred. The implied mass outflow rate from this wind, can be well constrained, and is 2 - 5 % of the mass accretion rate. If the mass outflow rate scaling with accretion rate is representative of all quasars, our results imply that warm absorbers in powerful quasars are unlikely to produce important evolutionary effects on their larger environment, unless we are observing the winds before they get fully accelerated. Only in such a scenario can AGN winds be important for cosmic feedback. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57103244 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.32
