Description
HESS J1857+026 is an extended gamma-ray source discovered by H.E.S.S., and identified as a pulsar wind nebula (PWN) candidate associated with PSR J1856+0245. MAGIC performed a follow-up observation, and two gamma-ray sources, called MAGIC J1857.2+0263 and MAGIC J1857.6+0297, were detected above 1 TeV. Taking advantage of 11 years of Fermi-LAT data, we re-analyze the region around HESS J1857+026 in the energy range of 0.5-500 GeV. In this work, we perform the energy-dependent extension analysis of HESS J1857+026 for the first time and present the results of spectral analysis.
