Correlated variability in the blazar 3C 454.3
E. W. Bonning, C. Bailyn, C. M. Urry +7
The blazar 3C 454.3 was revealed by the Fermi Gamma-ray Space Telescope to be in an exceptionally high flux state in July 2008. Accordingly, we performed a multi-wavelength monitor…
An Infrared Study of the Large-scale Jet in Quasar PKS 1136-135
Y. Uchiyama, C. M. Urry, P. Coppi +6
We present Spitzer IRAC imaging of the large-scale jet in the quasar PKS 1136-135 at wavelengths of 3.6 and 5.8 um, combined with previous VLA, HST, and Chandra observations. We cl…
Shedding New Light on the 3C 273 Jet with the Spitzer Space Telescope
Y. Uchiyama, C. M. Urry, C. C. Cheung +7
We have performed infrared imaging of the jet of the quasar 3C 273 at wavelengths 3.6 and 5.8 microns with the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. When com…
The Role of Gas in the Merging of Massive Black Holes in Galactic Nuclei. II. Black Hole Merging in a Clumpy Disk
Andres Escala, Richard B. Larson, Paolo S. Coppi +1
Using 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 the very massive nuclear ga…
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…
