Description
We perform simulations of Cherenkov Telescope Array (CTA) observations
of a young supernova remnant RX J1713.7−3946. This target is not only
one of the brightest sources ever discovered in very high-energy (VHE)
gamma-rays but also well observed in other wavebands. In X-rays, the
emission is dominated by synchrotron radiation, which links directly
to the existence of high-energy electrons. Radio observations of CO
and HI gas have revealed a highly inhomogeneous medium surrounding the
SNR, such as clumpy molecular clouds. Therefore gamma-rays from
hadronic interactions are naturally expected. However, the spectrum in
GeV energy range measured by Fermi/LAT indicates more typical of
leptonic emission from accelerated electrons. Despite lots of
multi-wavelength information, the competing interpretations have led
to much uncertainty in the quest of unraveling the true origin of the
gamma-ray emission from RX J1713.7--3946. CTA will achieve highest
performance ever in sensitivity, angular resolution, and energy
resolution. We estimate CTA capability to examine the emission
mechanisms of the gamma-rays through simulated spatial distribution,
spectra, and their time variation.
