X-Ray Polarimetry of Magnetic Turbulence and Cosmic Rays in Supernova Remnants

Abstract

Young supernova remnants (SNRs) are effective accelerators of charged particles. Particle acceleration is accompanied by the amplification of turbulent magnetic fields. The structure of SNR synchrotron intensity and polarization maps is sensitive to features of this field, especially in the X-ray energy band. Numerical modeling of synchrotron SNR maps is performed for different models of magnetic turbulence. The capabilities of a new-generation IXPE polarimeter designed to study magnetic turbulence in the vicinity of SNRs are discussed.
