New Results on Particle Acceleration in the Centaurus A Jet and Counterjet from a Deep Chandra Observation

We present new deep Chandra observations of the Centaurus A jet, with a combined on-source exposure time of 719 ks. These data allow detailed X-ray spectral measurements to be made along the jet out to its disappearance at 4.5 kpc from the nucleus. We distinguish several regimes of high-energy particle acceleration; while the inner part of the jet is dominated by knots and has properties consistent with local particle acceleration at shocks, …
