A significant excess in major merger rate for AGNs with the highest Eddington ratios at z<0.2
V. Marian, K. Jahnke, I. Andika +16
Observational studies are increasingly finding evidence against major mergers being the dominant mechanism responsible for triggering AGN. After studying the connection between maj…
Probing the Nature of High Redshift Weak Emission Line Quasars: A Young Quasar with a Starburst Host Galaxy
Irham Taufik Andika, Knud Jahnke, Masafusa Onoue +15
We present the discovery of PSO J083.8371+11.8482, a weak emission line quasar with extreme star formation rate at . This quasar was selected from Pan-STARRS1, UHS, and u…
Limits to Rest-Frame Ultraviolet Emission From Far-Infrared-Luminous z~6 Quasar Hosts
Madeline A. Marshall, Mira Mechtley, Rogier A. Windhorst +20
We report on a Hubble Space Telescope search for rest-frame ultraviolet emission from the host galaxies of five far-infrared-luminous quasars and the hot-dust…
Major mergers are not the dominant trigger for high-accretion AGNs at z = 2
V. Marian, K. Jahnke, M. Mechtley +8
Research over the past decade has shown diminishing empirical evidence for major galaxy mergers being a dominating or even important mechanism for the growth of supermassive black…
Color gradients reflect an inside-out growth in early-type galaxies of the cluster MACS J1206.2-0847
Victor Marian, Bodo Ziegler, Ulrike Kuchner +1
We use color gradients to explore the evolution of early-type galaxies in the core of the massive galaxy cluster MACS J1206.2-0847 at z = 0.44. We used data from the CLASH and CLAS…
