Almudena Prieto Sueli Viegas Física, Astronomía y Matemáticas LINE: FORMATION GALAXIES: SEYFERT INFRARED: GALAXIES The ISO coronal line spectrum of a sample of the brightest known Seyfertgalaxies is presented and modeled. ISO observations of [O IV] 25.9 , [Ne V] 14.3, [Mg VIII] 3.02 and [Si IX] 2.58 lines are presented; their relationship withthe ionizing spectrum from 50 to 300 eV is investigated. Pure photoionizationmodels reproduce the line ratios, setting ranges for the ionization parameter andthe optical depth of the emitting clouds. On the basis of the available data alone itis not possible to distinguish between a power-law or a blackbody as the intrinsicshape of the UV ionizing spectrum. However, for the brightest Seyferts analyzed,NGC 1068, Circinus and NGC 4151, a blackbody UV continuum is favored. 2000 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57100981 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.9 |
