Abstract

We describe asymmetrical features in a long exposure X-ray map of M 87 made with the ROSAT High Resolution Imager (HRI). A bright triangular region is marked by a linear ‘spur’ along one edge. The structure of this spur suggests an interpretation of a tangential view of a shock front 18 kpc long. None of the brighter features are spatially coincident with radio or optical structures so we concur with earlier investigators that most of the emission arises from thermal processes.
