High-energy particle acceleration at the radio-lobe shock of Centaurus A

J. H. Croston, R. P. Kraft, M. J. Hardcastle +19

We present new results on the shock around the southwest radio lobe of Centaurus A using data from the Chandra Very Large Programme observations. The X-ray spectrum of the emission…

A Chandra Study of the Lobe/ISM Interactions Around the Inner Radio Lobes of Centaurus A: Constraints on the Temperature Structure and Transport Processes

R. P. Kraft, P. E. J. Nulsen, M. Birkinshaw +6

We present results from deeper {\em Chandra} observations of the southwest radio lobe of Centaurus A, first described by Kraft et al. (2003). We find that the sharp X-ray surface b…

Empirical relation between angular momentum transport and thermal-to-magnetic pressure ratio in shearing box simulations

Eric G. Blackman, Robert F. Penna, Peggy Varniere

By combining data from different published 3-D simulations of Keplerian shearing boxes unstable to the magnetorotational instability (MRI), we highlight tight anti-correlations bet…
