Spectrum and Location of Ongoing Extreme Particle Acceleration in Cassiopeia A

Spectrum and Location of Ongoing Extreme Particle Acceleration in Cassiopeia A

Young supernova remnants (SNRs) are believed to be the origin of energetic cosmic rays (CRs) below the “knee” of their spectrum at ∼3 PeV (10 ^15 eV). Nevertheless, the precise location, duration, and operation of CR acceleration in young SNRs are open questions. Here, we report on multiepoch X-ray...
