AEGIS: Demographics of X-ray and Optically Selected AGNs
Renbin Yan, Luis C. Ho, Jeffrey A. Newman +19
We develop a new diagnostic method to classify galaxies into AGN hosts, star-forming galaxies, and absorption-dominated galaxies by combining the [O III]/Hbeta ratio with rest-fram…
Morphologies of Radio, X-Ray, and Mid-Infrared Selected AGN
Roger L. Griffith, Daniel Stern
We investigate the optical morphologies of candidate active galaxies identified at radio, X-ray, and mid-infrared wavelengths. We use the Advanced Camera for Surveys General Catalo…
Spectroscopic confirmation of a galaxy cluster associated with 7C1756+6520 at z=1.416
Audrey Galametz, Daniel Stern, S. Adam Stanford +4
We present spectroscopic follow-up of an overdensity of galaxies photometrically selected to be at 1.4<z<2.5 found in the vicinity of the radio galaxy 7C1756+6520 at z=1.4156. Usin…
Ultracool Field Brown Dwarf Candidates Selected at 4.5 microns
Peter R. M. Eisenhardt, Roger L. Griffith, Daniel Stern +14
We have identified a sample of cool field brown dwarf candidates using IRAC data from the Spitzer Deep, Wide-Field Survey (SDWFS). The candidates were selected from 400,000 SDWFS s…
The Effects of an AGN on Host Galaxy Colour and Morphology Measurements
C. M. Pierce, J. M. Lotz, J. R. Primack +11
We assess the effects of simulated active galactic nuclei (AGNs) on the colour and morphology measurements of their host galaxies. To test the morphology measurements, we select a…
Mid-Infrared Variability from the Spitzer Deep, Wide-Field Survey
Szymon Kozlowski, Christopher S. Kochanek, Daniel Stern +30
We use the multi-epoch, mid-infrared Spitzer Deep, Wide-Field Survey to investigate the variability of 474,179 objects in 8.1 deg^2 of the NDWFS Bootes field. We perform a Differen…
