Abstract:
'The young star clusters/star forming regions have been believed to be the Galactic CRs contributors. As the CR acceleration sites, the collective effect of stellar winds and/or supernova activity in the young stellar associations can produce a large-scale shock, which will accelerate the particles up to energies of hundreds of TeV. W49A is one of the massive and luminous star forming region in the Galaxy and one of the richest clusters known. Using the Fermi-LAT Pass 8 data, here we report the detection of the gamma-ray emission around W49A.'
