15 Jun 2005 | | Subject: | astro-ph | | Affiliation: | 1 and 2), C. Iserlohe , A. Eckart , W. Voges ( University of Cologne Germany, ESO Germany, Max-Planck Institute for extraterrestrial Physics Germany | | Abstract: | We will present first results of ESO-VLT AO-assisted integral-field spectroscopy of a sample of X-ray bright AGN with redshifts of 0.04 < z < 1. We constructed this sample by cross-correlating the SDSS and ROSAT surveys and utilizing typical AO constraints. This sample allows for a detailed study of the NIR properties of the nuclear and host environments with high spectral resolution on the 100 pc scale. These objects can then be compared directly to the local (z<0.01) galaxy populations (observed without AO) at the same linear scale. As a current example, we will present observations of the z=0.034 Seyfert 1.8 galaxy Mrk 609 with the new AO-assisted integral-field spectrometer SINFONI at the VLT. The successful observations show, that in the future - while having observed more objects - we will be able to determine the presence, frequency and importance of nuclear bars and/or circum-nuclear star forming rings in these objects and address the question of how these X-ray luminous AGN and their hosts are linked to optically/UV-bright QSOs, low-z QSOs/radio galaxies, or ULIRGs. | | Source: | arXiv, astro-ph/0506356 | | Services: | Forum | Review | PDF | Favorites | |
