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…
Misalignment between cold gas and stellar components in early-type galaxies
O. Ivy Wong, K. Schawinski, G. I. G. Józsa +5
Recent work suggests blue ellipticals form in mergers and migrate quickly from the blue cloud of star-forming galaxies to the red sequence of passively evolving galaxies, perhaps a…
Galaxy Zoo: Evidence for Diverse Star Formation Histories through the Green Valley
R. J. Smethurst, C. J. Lintott, B. D. Simmons +10
Does galaxy evolution proceed through the green valley via multiple pathways or as a single population? Motivated by recent results highlighting radically different evolutionary pa…
