Title: THE CENTAURUS A FILAMENTS: PROBING A JET/ISM INTERACTION
Observer: EVANS
Subject Category: Active Galaxies and Quasars
Seq: 700111 ObsId: 00806
Long-term Plan bin: 20-Jan-2000
ABSTRACT
The nearby radio galaxy Centaurus A contains the closest extragalactic jet that can be studied in X-rays. In particular, the Cen A filaments offer a unique laboratory to investigate the detailed physics of the interaction of a jet of relativistic plasma with a dense cloud in the interstellar medium of the galaxy. We intend to prove whether the optical filamentary emission is excited by radiative shocks or by the UV radiation from the nuclear source. The predicted X-ray emission from the fast shock model is just below the sensitivity limit of previous searches, and is expected to be concentrated into thin filamentary sheets. If X-rays remain undetected by this measurement, the excitation mechanism has to be due to hard photons.
