Minimum Spanning Tree cluster analysis of the LMC region above 10 GeV:
  detection of the SNRs N 49B and N 63A
  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.
