Faint COSMOS AGN at z~3.3 - I. Black Hole Properties and Constraints on Early Black Hole Growth

Benny Trakhtenbrot, Francesca Civano, C. Megan Urry +9

We present new Keck/MOSFIRE K-band spectroscopy for a sample of 14 faint, X-ray-selected active galactic nuclei (AGNs) in the COSMOS field. The data cover the spectral region surro…

An Over-Massive Black Hole in a Typical Star-Forming Galaxy, 2 Billion Years After the Big Bang

Benny Trakhtenbrot, C. Megan Urry, Francesca Civano +6

Supermassive black holes (SMBHs) and their host galaxies are generally thought to coevolve, so that the SMBH achieves up to about 0.2 to 0.5% of the host galaxy mass in the present…

Stellar Populations of Barred Quiescent Galaxies

Edmond Cheung, Charlie Conroy, E. Athanassoula +10

Selecting centrally quiescent galaxies from the Sloan Digital Sky Survey (SDSS) to create high signal-to-noise (>100) stacked spectra with minimal emission line contamination, we a…

Major Mergers Host the Most Luminous Red Quasars at z ~ 2: A Hubble Space Telescope WFC3/IR Study

Eilat Glikman, Brooke Simmons, Madeline Mailly +3

We used the Hubble Space Telescope WFC3 near-infrared camera to image the host galaxies of a sample of eleven luminous, dust-reddened quasars at z ~ 2 -- the peak epoch of black ho…

Galaxy Zoo: the dependence of the star formation-stellar mass relation on spiral disk morphology

Kyle W. Willett, Kevin Schawinski, Brooke D. Simmons +9

We measure the stellar mass-star formation rate relation in star-forming disk galaxies at z<0.085, using Galaxy~Zoo morphologies to examine different populations of spirals as clas…

Galaxy Zoo: the effect of bar-driven fueling on the presence of an active galactic nucleus in disc galaxies

Melanie A. Galloway, Kyle W. Willett, Lucy F. Fortson +7

We study the influence of the presence of a strong bar in disc galaxies which host an active galactic nucleus (AGN). Using data from the Sloan Digital Sky Survey and morphological…
