TeV gamma-ray survey of the northern sky using the ARGO-YBJ experiment
Abstract
The ARGO-YBJ experiment is an extensive air shower array with full coverage RPC detectors located at Yangbajing (4300 m asl, Tibet, China). It is operated with high duty cycle (>86%) and a large field of view ( 2sr). It continuously monitors the entire overhead sky at -ray energies above 0.1 TeV. In the talk, we will present the result of the northern sky survey (between declinations of -10 and 70) from an analysis of ~4 years of the ARGO-YBJ data (between July 2006 and February 2011). There are four known TeV sources observed with significance greater than 5 S.D.. The significance from Crab Nebula is more than 16 S.D.. 90% confidence level upper limits to the flux from all directions in the sky are also presented, which vary from 0.09 to 0.53 Crab unit for Crab-like point sources.
