论文摘要
我们使用12年的FERMI-LAT数据，在高于6和10 GEV的能量下，通过最小跨越树（MST）和DBSCAN算法介绍了大型麦芽云（LMC）区域的伽马射线天空图像的结果。发现了几个重要的簇，其中大多数与先前已知的伽马射线源相关。我们确认了先前对超新星残留物N 49b和n 63a的检测，发现与SNRS N 49，N 186D和N 44相关的新重要簇。这些来源是LMC中最明亮的X射线残留物之一，并且与核心循环超新星相对应与密集的Hii区域相互作用，表明大多数能量是hadronic sountrons of hadrons的较高源。
We present the results of a cluster search in the gamma-ray sky images of the Large Magellanic Cloud (LMC) region by means of the Minimum Spanning Tree (MST) and DBSCAN algorithms, at energies higher than 6 and 10 GeV, using 12 years of Fermi-LAT data. Several significant clusters were found, the majority of which associated with previously known gamma-ray sources. We confirm our previous detection of the Supernova Remnants N 49B and N 63A and found new significant clusters associated with the SNRs N 49, N 186D and N 44. These sources are among the brightest X-ray remnants in the LMC and corresponds to core-collapse supernovae interacting with dense HII regions, indicating that an hadronic origin of high energy photons is the most likely process.
