Galaxy Zoo: A Catalog of Overlapping Galaxy Pairs for Dust Studies
William C. Keel, Anna Manning, Benne W. Holwerda +5
Analysis of galaxies with overlapping images offers a direct way to probe the distribution of dust extinction and its effects on the background light. We present a catalog of 1990…
Moderate-Luminosity Growing Black Holes From 1.25 < z < 2.7: Varied Accretion In Disk-Dominated Hosts
Brooke D. Simmons, C. Megan Urry, Kevin Schawinski +2
We compute black hole masses and bolometric luminosities for 57 active galactic nuclei (AGN) in the redshift range 1.25 < z < 2.67, selected from the GOODS-South deep multi-wavelen…
The SDSS-III Baryon Oscillation Spectroscopic Survey: The Quasar Luminosity Function from Data Release Nine
Nicholas P. Ross, Ian D. McGreer, Martin White +39
We present a new measurement of the optical Quasar Luminosity Function (QLF), using data from the Sloan Digital Sky Survey-III: Baryon Oscillation Spectroscopic Survey (SDSS-III: B…
Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System
Megan E. Schwamb, Jerome A. Orosz, Joshua A. Carter +17
We report the discovery and confirmation of a transiting circumbinary planet (PH1b) around KIC 4862625, an eclipsing binary in the Kepler field. The planet was discovered by volunt…
A Quasar-Galaxy Mixing Diagram: Quasar Spectral Energy Distribution Shapes in the Optical to Near-Infrared
Heng Hao, Martin Elvis, Angela Bongiorno +19
We define a quasar-galaxy mixing diagram using the slopes of their spectral energy distributions (SEDs) from 1μm to 3000Å and from 1μm to 3μm in the rest frame. The mixing diagram…
Spectral Energy Distributions of Type 1 AGN in XMM-COSMOS Survey II - Shape Evolution
Heng Hao, Martin Elvis, Francesca Civano +18
The mid-infrared to ultraviolet (0.1 -- 10 ) spectral energy distribution (SED) shapes of 407 X-ray-selected radio-quiet type 1 AGN in the wide-field ``Cosmic Evolution Survey"…
