论文摘要
我们报告了在100 TEV中使用能量的天体物理伽马射线的搜索，以在定向和时间巧合的几个PEV范围内，以及HAWC（TEV Gamma Rays）和Icecube（中微子高于〜100 TEV）的公共警报。自2018年以来，在Baksan Neutminino天文台上使用地毯-2空调探测器进行了观察结果。自2018年以来，以“光子友好”模式工作。光子候选阵雨是通过其低音含量的低含量来选择的。尚未观察到光子候选物的显着过量，并且获得了与警报相关的伽马射线上的上限。对于具有良好观察条件的事件，光子的地毯2有效区域是Icecube有效区域的相同能量中微子的有效区域，因此约束开始探究银河系快速燃料中中微子的产生。
We report on the search of astrophysical gamma rays with energies in the 100 TeV to several PeV range arriving in directional and temporal coincidence with public alerts from HAWC (TeV gamma rays) and IceCube (neutrinos above ~100 TeV). The observations have been performed with the Carpet-2 air-shower detector at the Baksan Neutrino Observatory, working in the "photon-friendly" mode since 2018. Photon candidate showers are selected by their low muon content. No significant excess of the photon candidates have been observed, and upper limits on gamma-ray fluences associated with the alerts are obtained. For events with good viewing conditions, the Carpet-2 effective area for photons is of the order of the IceCube effective area for neutrinos of the same energy, so the constraints start to probe the production of neutrinos in fast flares of Galactic sources.
