Diffusive shock acceleration in the young supernova remnant G1.9+0.3


Primary authors


Abstract content

The very young Supernova remnant G1.9+0.3 is an interesting target for next generation gamma-ray observatories. So far the remnant is only detected in the radio and the X-ray bands but its young age and inferred shock speed of 14,000km/s should make it an efficient particle accelerator. We carry out spherical symmetric 1-D simulations where we simultaneously solve the transport equations for the cosmic rays, the hydrodynamical flow and the magnetic turbulence. With our test-particle simulations we are able to reproduce the observed radio and x-ray spectra together with the radio and x-ray profiles in the east-west direction and the observed radio-flux increase of about 1.2%/yr.
