Modeling the Multi-Wavelength Emission of Shell-Type Supernova Remnant RX J1713.7-3946

Understand

Emission mechanisms of the shell-type supernova remnant (SNR) RX J1713.7-3946 are studied with multi-wavelength observational data from radio, X-ray, GeV $\gamma$-ray to TeV $\gamma$-ray band.

• A Markov Chain Monte Carlo method is employed to explore the high-dimensional model parameter space systematically.
• Three scenarios for the $\gamma$-ray emission are investigated: the leptonic, the hadronic and a hybrid one.
• Thermal emission from the background plasma is also included to constrain the gas density, assuming ionization equilibrium, and a 2$\sigma$ upper limit of about 0.03 cm$^{-3}$ is obtained as far as thermal energies account for a significant fraction of the dissipated kinetic energy of the SNR shock.
