The relation between post-shock temperature, cosmic-ray pressure and cosmic-ray escape for non-relativistic shocks

Jacco Vink, R. Yamazaki, E. A. Helder +1

Supernova remnants are thought to be the dominant source of Galactic cosmic rays. This requires that at least 5% of the available energy is transferred to cosmic rays, implying a h…

Cosmic-Ray Acceleration Efficiency vs Temperature Equilibration: the Case of SNR 0509-67.5

E. A. Helder, D. Kosenko, J. Vink

We study the 0509-67.5 supernova remnant in the Large Magellanic Cloud with the VLT/FORS2 spectrograph. We detect a broad component in the H-alpha emission with a FWHM of 2680 \pm…

The kinematics and chemical stratification of the Type Ia supernova remnant 0519-69.0

Daria Kosenko, Eveline Helder, Jacco Vink

We present an analysis of the XMM-Newton and Chandra X-ray data of the young Type Ia supernova remnant 0519-69.0 in the Large Magellanic Cloud. We used data from both the Chandra A…
