|EXPECTATION ON OBSERVATION OF SUPERNOVA REMNANTS WITH THE LHAASO PROJECT|
|摘要||Supernova remnants (SNRs) are believed to be the most important acceleration sites for cosmic rays (CRs) below similar to 10(15) eV in the Galaxy. High-energy photons, either directly from the shocks of the SNRs or indirectly from the interaction between SNRs and the nearby clouds, are crucial probes for the CR acceleration. Big progresses on observations of SNRs have been achieved by space- and ground-based gamma-ray facilities. However, whether.-rays come from accelerated hadrons or not, as well as their connection with the CRs observed at Earth, remains in debate. Large High Altitude Air Shower Observatory (LHAASO), a next-generation experiment, is designed to survey the northern part of the very high energy gamma-ray sky from similar to 0.3 TeV to PeV with the sensitivity of less than or similar to 1% of the Crab Nebula flux. In this paper, we indicate that LHAASO will be dedicated to enlarging the gamma-ray SNR samples and improving the spectral and morphological measurements. These measurements, especially at energies above 30 TeV, will be important for us to finally understand the CR acceleration in SNRs.|
