Description

SN 1006 is a historic supernova remnant exhibiting a bilateral shape, with non-thermal X-ray and TeV emission more prominent in two polar cap regions aligned with the ambient magnetic field. Further, a large-scale ambient density gradient is observed to be roughly perpendicular to the magnetic axis. We model the multi-wavelength spectral and spatial properties of each quadrant in SN 1006 using a self-consistent, semi-analytical model of non-linear particle acceleration derived from kinetic plasma simulations, and compare to the latest multi-wavelength observations. Such a spatially-resolved analysis allows us to investigate how CR acceleration depends on shock obliquity and how the hadronic/leptonic nature of gamma-ray emission depends on the ambient density.
