Broadband γ-Ray Spectrum of Supernova Remnant Cassiopeia A
The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius of $\sim 2\mathop{.}\limits^{^{\prime} }5$ . Although no extension of this source has been detected in the γ -ray band, using more than 1000 days of LHAASO data above...
