An X-ray Selected AGN at z=4.6 Discovered by the CYDER Survey
Ezequiel Treister, Francisco J. Castander, Thomas J. Maccarone +4
We present the discovery of a high redshift, X-ray selected AGN by the Calan-Yale Deep Extragalactic Research (CYDER) survey: CXOCY J033716.7-050153, located at , the secon…
The Role of Gas in the Merging of Massive Black Holes in Galactic Nuclei. I. Black Hole Merging in a Spherical Gas Cloud
Andres Escala, Richard B. Larson, Paolo S. Coppi +1
Using high-resolution SPH numerical simulations, we investigate the effects of gas on the inspiral and merger of a massive black hole binary. This study is motivated by both observ…
New Quasars Detected via Variability in the QUEST1 Survey
A. W. Rengstorf, S. L. Mufson, C. Abad +31
By observing the high galactic latitude equatorial sky in drift scan mode with the QUEST (QUasar Equatorial Survey Team) Phase 1 camera, multi-bandpass photometry on a large strip…
