The Host Galaxy and The Extended Emission-Line Region of The Radio Galaxy 3C 79
Hai Fu, Alan Stockton
We present extensive ground-based spectroscopy and HST imaging of 3C79, an FR II radio galaxy associated with a luminous extended emission-line region (EELR). Surface brightness mo…
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…
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…
Morphologies and Color Gradients of Luminous Evolved Galaxies at z~1.5
Elizabeth J. McGrath, Alan Stockton, Gabriela Canalizo +2
We have examined in detail the morphologies of seven z~1.5 passively evolving luminous red galaxies using high resolution HST NICMOS and ACS imaging data. Almost all of these galax…
A Common Origin for Quasar Extended Emission-Line Regions and Their Broad-Line Regions
Hai Fu, Alan Stockton
We present a correlation between the presence of luminous extended emission-line regions (EELRs) and the metallicity of the broad-line regions (BLRs) of low-redshift quasars. The r…
