The radio-lobe shock of Centaurus A: particle acceleration and environmental impact
Presenter: Judith Croston (University of Hertfordshire)
Abstract: Centaurus A is the first system in which direct evidence for a strong shock associated with radio-lobe expansion has been found, and is the nearest and most dramatic example of a jet / environment interaction. Our new, very deep Chandra observations have revealed that the X-ray emission from the shock front is dominated by synchrotron radiation, with properties similar to those seen in some supernova remnants. I will discuss the implications of these results for particle acceleration at the shock, for Centaurus A as a source of TeV radiation and UHECRs, and for shock heating in nearby and more distant galaxies.
