A survey of X-ray emission from 100 kpc radio jets
Daniel A Schwartz, Herman L Marshall, Diana M Worrall +8
We have completed a Chandra snapshot survey of 54 radio jets that are extended on arcsec scales. These are associated with flat spectrum radio quasars spanning a redshift range z=0…
Missing Gamma-Rays from kpc-scale AGN Jets: A Test of the IC/CMB Model
Eileen T. Meyer, Markos Georganopoulos, William B. Sparks +2
The physical origin of the X-ray emission in powerful quasar jets has been a long-standing mystery. Though these jets start out on the sub-pc scale as highly relativistic flows, we…
Measuring the jet power of flat spectrum radio quasars
Stanislav Shabala, Jesse Santoso, Leith Godfrey
We use frequency-dependent position shifts of flat spectrum radio cores to estimate the kinetic power of AGN jets. We find a correlation between the derived jet powers and AGN narr…
Very Long Baseline Interferometry with the SKA
Zsolt Paragi, Leith Godfrey, Cormac Reynolds +79
Adding VLBI capability to the SKA arrays will greatly broaden the science of the SKA, and is feasible within the current specifications. SKA-VLBI can be initially implemented by pr…
Dying radio galaxies in the LOFAR Lockman Hole
Marisa Brienza, Elizabeth Mahony, Raffaella Morganti +2
After the jets have switched off, radio galaxies undergo a fading phase which is often named the dying phase. The luminosity evolution of the remnant plasma during this period is s…
Ruling out IC/CMB X-rays in PKS 0637-752 and the Implications for TeV Emission from Large-Scale Quasar Jets
Eileen T. Meyer, Markos Georganopoulos, William B. Sparks +3
The Chandra X-ray observatory has discovered dozens of resolved, kiloparsec-scale jets associated with powerful quasars in which the X-ray fluxes are observed to be much higher tha…
