Evidence of Gradients of Density and Magnetic Field in the Remnant of Tycho’s Supernova

open access: yesThe Astrophysical Journal
By using surface brightness maps of Tycho’s supernova remnant (SNR) in radio and X-rays, along with the properties of thermal and synchrotron emission, we have derived the postshock density and magnetic field (MF) strength distributions over the ...

Acceleration and Transport of the Unstable Cosmic-Ray Isotope 60Fe in Supernova-enriched Environments

open access: yesThe Astrophysical Journal
The unstable isotope ^60 Fe, with a half-life of 2.6 million years, is produced primarily in supernova explosions. The observed presence of ^60 Fe in cosmic rays and its detection in deep-sea crusts and sediments suggest two possible scenarios: either ...
