Deceleration from Entrainment in the jet of the quasar 1136-135?
F. Tavecchio, L. Maraschi, R. M. Sambruna +4
Modeling the multiwavelength emission of successive regions in the jet of the quasar PKS 1136-135 we find indication that the jet suffers deceleration near its end on a (deprojecte…
Spitzer Number Counts of AGN in the GOODS fields
Ezequiel Treister, C. Megan Urry, Jeffrey Van Duyne +7
We present mid-infrared observations of AGN in the GOODS fields, performed with the Spitzer Space Telescope. These are the deepest infrared and X-ray fields to date and cover a tot…
Obscured and Unobscured AGN Evolution and the X-ray background
Ezequiel Treister, C. Megan Urry, Paulina Lira
The Great Observatories Origins Deep Survey (GOODS) combines deep HST and Spitzer imaging with the deepest Chandra/XMM observations to probe obscured AGN at higher redshifts than p…
Deep Chandra and multicolor HST follow-up of the jets in two powerful radio quasars
R. Sambruna, M. Gliozzi, D. Donato +5
We present deep (70-80 ks) Chandra and multicolor HST ACS images of two jets hosted by the powerful quasars 1136-135 and 1150+497, together with new radio observations. The sources…
The Extended Chandra Deep Field-South Survey: Optical Properties of X-ray Detected Sources
Shanil Virani, Ezequiel Treister, C. Megan Urry +2
The Extended Chandra Deep Field-South (E-CDF-S) survey consists of 4 Chandra ACIS-I pointings and covers ~1100 square arcminutes (~0.3 deg^2) centered on the original CDF-S field t…
The Multiwavelength Survey by Yale-Chile (MUSYC): Survey Design and Deep Public UBVRIz' Images and Catalogs of the Extended Hubble Deep Field South
MUSYC Collaboration, E. Gawiser, P. G. van Dokkum +25
We present UBVRIz' optical images of the 0.32 square degree Extended Hubble Deep Field South. This is one of four fields comprising the MUSYC survey, which is optimized for the stu…
Spitzer IRAC Imaging of the Relativistic Jet from Superluminal Quasar PKS 0637-752
Y. Uchiyama, C. M. Urry, J. Van Duyne +5
Emission from the relativistic jet located at hundreds of kpc from the core of the superluminal quasar PKS 0637-752 was detected at 3.6 and 5.8 microns with the Infrared Array Came…
AGN Host Galaxies at z~0.4-1.3 : Bulge-dominated and Lacking Merger-AGN Connection
N. A. Grogin, C. J. Conselice, E. Chatzichristou +13
We investigate morphological structure parameters and local environments of distant moderate-luminosity active galactic nucleus (AGN) host galaxies in the overlap between the HST/A…
Black Hole Masses and Host Galaxy Evolution of Radio-loud Active Galactic Nuclei
J. -H. Woo, C. M. Urry, R. P. van der Marel +2
We report stellar velocity dispersion measurements for a sample of 28 AGN host galaxies including our previous work. Using the mass-dispersion () and the fundamental…
The Extended Chandra Deep Field-South Survey: X-ray Point-Source Catalog
Shanil Virani, Ezequiel Treister, C. Megan Urry +1
The Extended Chandra Deep Field-South (ECDFS) survey consists of 4 Chandra ACIS-I pointings and covers 1100 square arcminutes ( 0.3 deg) centered on the orig…
