Supernova remnants (SNRs) are nebulae formed after massive stars (more than eight solar masses) or specific binary systems undergo supernova explosions in the final stages of their lives. Since they profoundly influence interstellar space through shock waves at speeds of 10,000 km\/s and provide heavy elements essential for life, SNRs are one of the most important phenomena in understating the universe. SNRs are also believed to be the primary sources of Galactic cosmic rays, mainly consisting of relativistic protons, because high-velocity shock waves offer an ideal site for diffusive shock acceleration (DSA). However, due to insufficient observational evidence, the principal acceleration sites of cosmic rays are still being debated. I am conducting multiwavelength observational studies, mainly using radio telescopes, X-ray astronomical satellites, and gamma-ray telescopes to elucidate the origin of cosmic rays, a century-old mystery in modern astrophysics.<\/p>\r\n
