Chandra Reveals Twin X-ray Jets in the Powerful Fr Ii Radio Galaxy 3c 353
We report X-ray imaging of the powerful FR II radio galaxy 3C 353 using the Chandra X-ray Observatory. 3C 353’s two 4′′-wide and 2′-long jets allow us to study in detail the internal structure of the large-scale relativistic outflows at both radio and X-ray photon energies with the sub-arcsecond spatial resolution provided by the VLA and Chandra instruments. In a 90 ks Chandra observation, we h...
متن کاملFR II radio galaxies with z < 0 . 3 – I . Properties of jets , cores and hot spots
In previous papers we have discussed high-resolution observations of a large sample of powerful radio galaxies with z < 0.3. Jets are detected in up to 80 per cent of the sample, and radio cores in nearly all the objects; in addition, we are able to resolve the hot spots in most sources. In this paper we present measurements of the radio properties of these components. The prominences of the je...
متن کاملThe physics of jets in FR I radio galaxies
We model jets in low-luminosity (FR I) radio galaxies as intrinsically symmetrical, axisymmetric, decelerating relativistic flows with transverse velocity gradients. This allows us to derive velocity fields and the three-dimensional distributions of magneticfield ordering and rest-frame emissivity. A conservation-law analysis, combining the kinematic model with X-ray observations of the surroun...
متن کاملShock heating by FR I radio sources in galaxy clusters
Feedback by active galactic nuclei (AGN) is frequently invoked to explain the cut-off of the galaxy luminosity function at the bright end and the absence of cooling flows in galaxy clusters. Meanwhile, there are recent observations of shock fronts around radioloud AGN. Using realistic 3D simulations of jets in a galaxy cluster, we address the question what fraction of the energy of active galac...
متن کاملChandra discovery of 10 new x-ray jets associated with FR II radio core-selected AGNs in the Mojave sample
The Chandra X-ray Observatory has proven to be a vital tool for studying high-energy emission processes in jets associated with active galactic nuclei (AGNs). We have compiled a sample of 27 AGNs selected from the radio flux-limited MOJAVE (Monitoring of Jets in AGNs with VLBA Experiments) sample of highly relativistically beamed jets to look for correlations between X-ray and radio emission on...
