In 2023, a supernova burst in the Pinwheel galaxy, creating an ideal scenario for testing theories on cosmic ray acceleration. However, the Fermi Gamma-ray Space Telescope, which has been operational since 2008, did not detect the anticipated high-energy gamma rays. On May 18, 2023, the supernova named SN 2023ixf occurred about 22 million light-years away in Ursa Major, marking it as one o
