JWST's PEARLS: A z=6 quasar in a train-wreck galaxy merger system

Madeline A. Marshall, Rogier A. Windhorst, Giovanni Ferrami +35

We present JWST NIRSpec integral field spectroscopy observations of the z=5.89 quasar NDWFS J1425+3254 from 0.6-5.3 microns, covering the rest-frame ultraviolet and optical at a sp…

Observing the host galaxies of high-redshift quasars with JWST: predictions from the BlueTides simulation

Madeline A. Marshall, J. Stuart B. Wyithe, Rogier A. Windhorst +5

The bright emission from high-redshift quasars completely conceals their host galaxies in the rest-frame ultraviolet/optical, with detection of the hosts in these wavelengths eludi…

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…

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…

Probing the Bright End of the Rest-Frame Ultraviolet Luminosity Function at z = 8-10 with Hubble Pure-Parallel Imaging

Sofía Rojas-Ruiz, Steven L. Finkelstein, Micaela B. Bagley +5

Looking for bright galaxies born in the early universe is fundamental to investigating the Epoch of Reionization, the era when the first stars and galaxies ionized the intergalacti…

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…
