Enhanced TeV gamma ray flux from the Crab Nebula observed by the ARGO-YBJ experiment
Abstract
Following the detection by Fermi (ATel#4239) of enhanced gamma ray emission from the Crab Nebula region on July 3rd, 2012, we report on the observation performed in the same day by the ARGO-YBJ experiment. ARGO-YBJ is a full coverage air shower detector located at the Yangbajing Cosmic Ray Laboratory in Tibet (China) at 4300 m a.s.l. It continuously monitors the northern sky at energies above 0.3TeV with a field of view of about 2 sr and a duty cycle of about 85%.
