ARGO‐YBJ is the first EAS detector combining a very high mountain altitude (4300 m a.s.1.) to a “full coverage” detection surface.

Abstract

ARGO‐YBJ is the first EAS detector combining a very high mountain altitude (4300 m a.s.1.) to a “full coverage” detection surface. These features allow ARGO‐YBJ to work with an energy threshold as low as a few hundreds GeV. The high duty cycle and the large field of view (∼2 sr) make ARGO‐YBJ suitable to monitor the gamma ray sky, searching for unknown sources and unexpected events, like Active Galactic Nuclei flaring episodes or high energy Gamma Ray Bursts. In this paper we present the first observations of ARGO‐YBJ concerning gamma ray astronomy, in particular the detection of the Crab Nebula and the blazar Markarian 421 during the 2006 and 2008 outbursts, and the results of a search for Gamma Ray Bursts emission in the GeV energy range using the scaler mode technique.
