Nonthermal properties of supernova remnant G1.9+0.3.

Abstract (from CDS):

The properties of the–presumably–youngest Galactic supernova remnant (SNR) G1.9+0.3 are investigated within the framework of nonlinear kinetic theory of cosmic ray acceleration in SNRs. The observed angular size and expansion speed as well as the radio and X-ray emission measurements are used to determine relevant physical parameters of this SNR. Under the assumption that SNR G1.9+0.3 is the result of a Type Ia supernova near the Galactic center (at the distance d = 8.5 kpc), the nonthermal properties are calculated. In particular, the expected TeV gamma-ray spectral energy density is predicted to be as low as εγFγ≈ 5x10–15 erg/cm2/s, strongly dependent (Fγ{vprop} d–11) upon the source distance d.
