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. ... 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. go back . ...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

... While there is practically no detector noise present at energies above , X-ray data below are considerably contaminated by noise events, which become more and more dominant towards the lowest transmitted energies (Fig. ... Investigations of 40 hours of in-orbit calibration data with the filter wheel closed, taken over a period of more than two years, showed that the noise properties vary with position and energy, but are fairly stable in time for most areas on the detector. ...
