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…
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 XMM-Newton view of gamma-ray loud active nuclei
L. Foschini, G. Ghisellini, C. M. Raiteri +8
Notwithstanding the big efforts devoted to the investigation of the mechanisms responsible for the high-energy (E>100 MeV) gamma-ray emission in active galactic nuclei (AGN), the d…
XMM-Newton view of PKS 2155-304: hardness ratio and cross-correlation analysis of EPIC pn observations
Y. H. Zhang, A. Treves, L. Maraschi +2
With currently available XMM-Newton EPIC pn observations spanned over about 3 years, we present a detailed spectral and temporal variability of the 0.2--10 keV X-ray emission from…
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…
The XMM-LSS survey: The XMDS/VVDS 4 sigma catalogue
L. Chiappetti, M. Tajer, G. Trinchieri +15
We present a first catalogue of X-ray sources resulting from the central area of the XMM-LSS (Large Scale Structure survey). We describe the reduction procedures and the database t…
