Extended X-ray and Radio Structures around high-redshift (z~0.5-2) 3CRR sources
Abstract
X-rays probe the emission mechanisms, energetics, and feedback of powerful radio jets. Chandra observations of the 3CRR radio sources reveal extended emission in 31 objects. Chandra X-ray images were aligned with the radio contours to locate X-ray emission associated with the various radio structures as well as X-ray emission unassociated with the radio contours that may be detected due to hot gas emitting X-ray radiation in a cluster of galaxies containing the quasar. The radio-associated X-ray data are analysed by fitting the spectra and calculating the median flux for the emission within each radio knot or hotspot. The radio and X-ray fluxes for each radio structure (knot, hotspot, lobe) are then fit with synchrotron and Inverse Compton scattering models to estimate the physical conditions and energetics of the emitting plasma.
