Abstract

The ARGO-YBJ experiment is the first EAS detector combining a very high mountain altitude (4300 m a.s.l.) to a full coverage detection surface. These features allow ARGO-YBJ to work in the typical energy range of Cherenkov telescopes, with an energy threshold of a few hun- dreds GeV. The low threshold and the large field of view (<2 sr) make ARGO-YBJ suitable to monitor the gamma ray sky, searching for un- known sources and unexpected events, like Active Galactic Nuclei flaring episodes or high energy Gamma Ray Bursts. In this paper we present the preliminary results on Gamma Ray Astron- omy obtained with the events collected in the first months of data taking, in particular the detection of gamma rays from the Crab Nebula, the ob- servation of a Markarian 421 outburst in July-August 2006, and finally a search for Gamma Ray Bursts emission in the GeV energy range using the scaler mode technique.
