Abstract

'G4argo', a GEANT4-based simulation package for the ARGO-YBJ detector, is described in this paper. G4argo incorporates in the simulation the true RPC time resolution and another 0.5 ns time uncertainty which is introduced from the offline calibration of TDC. In addition, the correct RPC geometry and the true materials for the ARGO-YBJ experimental hall are implemented. As a result, G4argo simulation shows a very good agreement with real data.

Abstract

""The full coverage extensive air shower detector ARGO-YBJ, located in Tibet at 4300 m of altitude, has monitored the sky at gamma ray energy E>0.6TeV in the declination band from -10° to 70°. In 424 days the Crab Nebula and Mrk421 have been detected with a significance, respectively, of 7.0 and 8.0 standard deviations. The analysis of the cosmic ray background in the same sky band, has revealed the existence of a significant excess of the cosmic ray flux in two localized regions of angular size 10°30°, confirming previous indications. The origin of such excesses is still unexplained. Concerning the gamma ray sources, the measured spectrum of the Crab Nebula is dN\\\/dE=(3.7±0.8)×10-11E-2.67±0.25photonscm-2s-1TeV-1, in agreement with other experiments. During 2008 the observed Mrk421 flux was highly variable, with the strongest flares in MarchJune, in good correlation with X-ray data. One of the most intense flares occurred in the first half of June and has been deeply studied by different detectors in the energy range from optical to 100 MeV gamma rays, but only partially up to TeV energies, since the moonlight hampered the Cherenkov telescope measurements during the second and most intense part of the emission. Our data complete these observations, with the detection of a signal of intensity of about 7 Crab units on June 1113, with a statistical significance of 4.2 standard deviations. The observed flux is consistent with a prediction made in the framework of the Synchrotron Self-Compton model, in which the flare is caused by a rapid acceleration of leptons in the jet. ""

Abstract

""The ARGO-YBJ experiment at YangBaJing in Tibet (4300m a.s.l.) has been taking data with its full layout since October 2007. Here we present a few significant results obtained in gamma-ray astronomy and cosmic-ray physics. Emphasis is placed on the analysis of gamma-ray emission from point-like sources (Crab Nebula, MRK 421), on the preliminary limit on the antiproton\\\/proton flux ratio, on the large-scale cosmic-ray anisotropy and on the proton-air cross-section. The performance of the detector is also discussed, and the perspectives of the experiment are outlined.""
