First Results from the Lick AGN Monitoring Project: The Mass of the Black Hole in Arp 151
Misty C. Bentz, Jonelle L. Walsh, Aaron J. Barth +24
We have recently completed a 64-night spectroscopic monitoring campaign at the Lick Observatory 3-m Shane telescope with the aim of measuring the masses of the black holes in 13 ne…
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…
Quasar Black Hole Masses from Velocity Dispersions
Gabriela Canalizo, Margrethe Wold, Mariana Lazarova +1
Much progress has been made in measuring black hole (BH) masses in (non-active) galactic nuclei using the tight correlation between stellar velocity dispersions (sigma) in galaxies…
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…
Morphologies of Two Massive Old Galaxies at z ~ 2.5
Alan Stockton, Elizabeth McGrath, Gabriela Canalizo +2
We present the results of NICMOS imaging of two massive galaxies photometrically selected to have old stellar populations at z ~ 2.5. Both galaxies are dominated by apparent disks…
