Abstract

We present the results of a cluster search in the \(\gamma \)-ray sky images of the Large Magellanic Cloud region by means of the Minimum Spanning Tree algorithm at energies higher than 10 GeV, using 9 years of Fermi-LAT data. Several significant clusters were found, the majority of which associated with previously known \(\gamma \)-ray sources. New significant clusters associated with the supernova remnants N 49B and N 63A are also found, and confirmed with a Maximum Likelihood analysis of the Fermi-LAT data.

Keywords

\(\gamma \)-rays: observations \(\gamma \)-rays: source detection
