Astronomers have used ESA's XMM-Newton spacecraft to investigate the overionized recombining plasma in a supernova remnant (SNR) known as IC 443. Results of this research, published August 12 on arXiv.org, deliver essential ...
Astronomers have succeeded for the first time in quantifying the proton and electron components of cosmic rays in a supernova remnant. At least 70% of the very-high-energy gamma rays emitted from cosmic rays are due to relativistic ...
