SEARCH for SOURCES of HIGH-ENERGY NEUTRONS with FOUR YEARS of DATA from the ICETOP DETECTOR
IceTop is an air-shower array located on the Antarctic ice sheet at the geographic South Pole. IceTop can detect an astrophysical flux of neutrons from Galactic sources as an excess of cosmic-ray air showers arriving from the source direction. Neutrons are undeflected by the Galactic magnetic field...
