- The X-ray view of the ionization cone in NGC 5252 Matteo Guainazzi Stefano Bianchi Massimo Cappi Mauro Dadina Giuseppe Malaguti Física, Astronomía y Matemáticas rays: galaxies Galaxies: active galaxies: nuclei galaxies: Seyfert galaxies: individual (NGC 5252) We present the results of a Chandra soft X-ray observation of the spectacular ionization cone in the nearby Seyfert 2 galaxy NGC 5252. As almost invariably observed in obscured AGN, the soft X-ray emission exhibitsa remarkable morphological coincidence with the ionized gas cone as traced by HST O[III] images. Energyresolvedimages and high-resolution spectroscopy suggest that the X-ray emitting gas is photoionized by theAGN, at least on scales as large as the innermost gas and stellar ring (≤3 kpc). Assuming that the whole coneis photoionized by the AGN, we reconstruct the history of the active nucleus in the last ~10 5 years. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57103232 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
