The Supernova Remnant RCW 86
July 2007 RCW 86 is a supernova remnant with a barrel-shaped shell, nicely visible in X-rays (top image), in the optical and in radio waves (Fig. 1). Concerning its age, two options are discussed…
Gamma Rays from W28 – an Old Supernova Remnant and Molecular Clouds
April 2007 It is a long-held idea that supernova remnants are acceleration sites for nucleonic cosmic rays. Indeed supernova shells are clearly seen as sources of high energy gamma rays (SOM 2005/01, SOM 2005/03),…
A Point-Like Gamma-Ray Source in Monoceros
February 2007 Previous H.E.S.S. results on the supernova remnants RX J1713.7-3946 and RX J0852.0-4622 have clearly demonstrated that supernova shock fronts are capable of accelerating particles to very high energies. Gamma rays are produced…
