8 Dec 2000 | Subject: | astro-ph | Affiliation: | 1,2), Ana Pérez-Garc’{i}a and José M. Rodr’{i}guez-Espinosa ( European Southern Observatory, Germany; Instituto de Astrof’{i}sica de Canarias, Spain | Abstract: | The relation between the X-ray emission, the infrared emission and the coronal line emission in a sample of the brightest known Seyfert galaxies is analyzed. A close relationship between the absorption-corrected soft X-ray emission and both the mid-infrared and the coronal line emission is found among the Seyfert type 2 objects studied in this work. Being both the coronal line and the X-ray emissions main tracers of the AGN activity, their relation with the mid-infrared emission adds further support to the claim that the mid-infrared emission is primarily due to dust heated directly by the central AGN. No apparent relationship between the soft X-ray emission and the coronal line and/or the mid-infrared emissions is seen within Seyfert 1 objects, the number of objects of this class in the sample is comparatively smaller though. That discrepancy is partially due to the fact that the soft X-ray emission in the Seyfert 1s is systematically larger by at least one order of magnitude than that in their Seyfert 2 counterparts. Finally, the hard X-ray emission in both Seyfert types shows unrelated to the mid-infrared and coronal line emissions. | Source: | arXiv, astro-ph/0101103 | Services: | Forum | Review | PDF | Favorites |
