High-redshift quasar host galaxies with adaptive optics
B. Kuhlbrodt, E. Orndahl, L. Wisotzki +1
We present K band adaptive optics observations of three high-redshift (z ~ 2.2) high-luminosity quasars, all of which were studied for the first time. We also bserved several point…
X-ray to UV Variability Correlation in MCG-6-30-15
P. Arevalo, I. Papadakis, B. Kuhlbrodt +1
We used a ~300 ks long XMM-Newton observation of the Seyfert 1 galaxy MCG-6-30-15 to study the correlation between the 0.2-10 keV X-ray and the 3000-4000 A bands. We found a signif…
Decomposition of AGN host galaxy images
B. Kuhlbrodt, L. Wisotzki, K. Jahnke
We describe an algorithm to decompose deep images of Active Galactic Nuclei into host galaxy and nuclear components. Currently supported are three galaxy models: A de-Vaucouleurs s…
Multiwavelength scaling relations for nuclei of Seyfert galaxies
M. Salvato, J. Greiner, B. Kuhlbrodt
We analyze an X-ray flux-limited, complete sample of 93 AGN at z< 0.1, selected from the ROSAT Bright Survey. Two thirds of the sample are Seyfert 1 galaxies (Sy1) and one third ar…
Quasar host galaxy star formation activity from multicolour data
K. Jahnke, B. Kuhlbrodt, L. Wisotzki
We investigate multicolour imaging data of a complete sample of 19 low redshift (z<0.2) quasar host galaxies. The sample was imaged in four optical (BVRi) and three near-infrared b…
On-axis spatially resolved spectroscopy of low redshift quasar host galaxies: HE 1503+0228 at z=0.135
F. Courbin, G. Letawe, P. Magain +8
We present the first result of a comprehensive spectroscopic study of quasar host galaxies. On-axis, spatially resolved spectra of low redshift quasars have been obtained with FORS…
