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…
How Mergers May Affect The Mass Scaling Relations Between Black Holes, Galaxies, and Other Gravitationally Bound Systems
Chien Y. Peng
Supermassive black hole (BH) masses (MBH) are strongly correlated with galaxy stellar bulge masses (Mbulge) and there are several ideas to explain the origin of this relationship.…
