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…
The merging/AGN connection: A case for 3D spectroscopy
S. F. Sanchez, L. Christensen, T. Becker +5
We discuss an ongoing study of the connection between galaxy merging/interaction and AGN activity, based on integral field spectroscopy. We focus on the search for AGN ionization i…
The B band luminosities of QSO host galaxies
K. Jahnke, L. Wisotzki
We report on the analysis of B band imaging data of 57 low-redshift QSOs and Seyfert 1 galaxies selected from the Hamburg/ESO-Survey, for which host galaxy dependent selection bias…
GEMS Imaging of Red Sequence Galaxies at z~0.7: Dusty or Old?
Eric F. Bell, Daniel H. McIntosh, Marco Barden +13
We have used the 30'x30' Hubble Space Telescope image mosaic from the Galaxy Evolution from Morphology and SEDs (GEMS) project in conjunction with the COMBO-17 deep photometric red…
Integral-field spectroscopy of the quadruple QSO HE 0435-1223: Evidence for microlensing
L. Wisotzki, T. Becker, L. Christensen +5
We present the first spatially resolved spectroscopic observations of the recently discovered quadruple QSO and gravitational lens HE0435-1223. Using the Potsdam Multi-Aperture Spe…
