Host galaxies of luminous z0.6 quasars: Major mergers are not prevalent at the highest AGN luminosities
C. Villforth, T. Hamilton, M. M. Pawlik +10
Galaxy interactions are thought to be one of the main triggers of Active Galactic Nuclei (AGN), especially at high luminosities, where the accreted gas mass during the AGN lifetime…
Extremely Red Quasars in BOSS
Fred Hamann, Nadia L. Zakamska, Nicholas Ross +11
Red quasars are candidate young objects in an early transition stage of massive galaxy evolution. Our team recently discovered a population of extremely red quasars (ERQs) in the B…
Space Telescope and Optical Reverberation Mapping Project. IV. Anomalous behavior of the broad ultraviolet emission lines in NGC 5548
M. R. Goad, K. T. Korista, G. De Rosa +99
During an intensive Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) UV monitoring campaign of the Seyfert~1 galaxy NGC 5548 performed from 2014 February to July, the…
Shape asymmetry: a morphological indicator for automatic detection of galaxies in the post-coalescence merger stages
M. M. Pawlik, V. Wild, C. J. Walcher +5
We present a new morphological indicator designed for automated recognition of galaxies with faint asymmetric tidal features suggestive of an ongoing or past merger. We use this ne…
