Fueling QSOs: The Relevance of Mergers
Nicola Bennert, Gabriela Canalizo, Bruno Jungwiert +4
To study the relevance of mergers for the fueling of QSOs, we are currently conducting an HST imaging campaign of a sample of QSO host galaxies classified as ellipticals in the lit…
Evidence for Merger Remnants in Early-Type Host Galaxies of Low-Redshift QSOs
Nicola Bennert, Gabriela Canalizo, Bruno Jungwiert +4
We present results from a pilot HST ACS deep imaging study in broad-band V of five low-redshift QSO host galaxies classified in the literature as ellipticals. The aim of our study…
Searching for Mergers in Early-Type QSO Host Galaxies and a Control Sample of Inactive Ellipticals
Nicola Bennert, Gabriela Canalizo, Bruno Jungwiert +4
We present very deep HST/ACS images of five QSO host galaxies, classified as undisturbed ellipticals in earlier studies. For four of the five objects, our images reveal strong sign…
Spectacular Shells in the Host Galaxy of the QSO MC2 1635+119
Gabriela Canalizo, Nicola Bennert, Bruno Jungwiert +4
We present deep HST/ACS images and Keck spectroscopy of MC2 1635+119, a QSO hosted by a galaxy previously classified as an undisturbed elliptical. Our new images reveal dramatic sh…
Properties of the Narrow-Line Region in Seyfert Galaxies
Nicola Bennert, Bruno Jungwiert, Stefanie Komossa +3
We study the narrow-line region (NLR) of six Seyfert-1 and six Seyfert-2 galaxies by means of spatially resolved optical spectroscopy and photoionization modelling. From spatially…
Size and properties of the narrow-line region in Seyfert-1 galaxies from spatially-resolved optical spectroscopy
Nicola Bennert, Bruno Jungwiert, Stefanie Komossa +3
Spatially resolved emission-line spectroscopy is a powerful tool to determine the physical conditions in the narrow-line region (NLR) of active galactic nuclei (AGNs). We recently…
