本文报道了Fermi伽玛射线空间望远镜大面积望远镜（LAT）对超新星遗迹IC 443 （G189.1+3.0）在200 MeV - 50 GeV波段的观测结果。IC 443是一个壳型信噪比，具有混合形态，位于银河系外平面，在x射线，GeV和TeV伽玛射线波段中检测到高能发射。过去的观测表明，IC 443一直在与周围的星际物质相互作用。密集的激波分子云与EGRET、MAGIC和VERITAS探测到的GeV-TeV伽玛射线发射区域之间的接近表明，宇宙射线（CR）粒子被信噪比加速了。利用LAT提供的高伽马射线统计量和广泛的能量覆盖范围，我们准确地表征了IC 443加速下CRs产生的伽马射线发射。发射区在θ68 = 0的能带上扩展。°27±0°01（stat）±0。°03（sys）为假定的二维高斯剖面，与VERITAS的扩展源区域几乎完全重叠。它的质心明显偏离了已知的脉冲星风星云（PWN），这表明PWN不是当前能带的主要贡献者。观测到的光谱连续改变其幂律斜率，并平滑地延续到MAGIC和VERITAS数据点。联合伽马射线谱（200mev）
We report observation of the supernova remnant (SNR) IC 443 (G189.1+3.0) with the Fermi Gamma-ray Space Telescope Large Area Telescope (LAT) in the energy band between 200 MeV and 50 GeV. IC 443 is a shell-type SNR with mixed morphology located off the outer Galactic plane where high-energy emission has been detected in the X-ray, GeV and TeV gamma-ray bands. Past observations suggest IC 443 has been interacting with surrounding interstellar matter. Proximity between dense shocked molecular clouds and GeV–TeV gamma-ray emission regions detected by EGRET, MAGIC, and VERITAS suggests an interpretation that cosmic-ray (CR) particles are accelerated by the SNR. With the high gamma-ray statistics and broad energy coverage provided by the LAT, we accurately characterize the gamma-ray emission produced by the CRs accelerated at IC 443. The emission region is extended in the energy band with θ68 = 0.°27 ± 0.°01(stat) ± 0.°03(sys) for an assumed two-dimensional Gaussian profile and overlaps almost completely with the extended source region of VERITAS. Its centroid is displaced significantly from the known pulsar wind nebula (PWN) which suggests the PWN is not the major contributor in the present energy band. The observed spectrum changes its power-law slope continuously and continues smoothly to the MAGIC and VERITAS data points. The combined gamma-ray spectrum (200 MeV
