We present the first catalog of gamma-ray sources emitting above 56 and 100 TeV with data from the High Altitude Water Cherenkov Observatory, a wide field-of-view observatory capable of detecting gamma rays up to a few hundred TeV. Nine sources are observed above 56 TeV, all of which are likely galactic in origin. Three sources continue emitting past 100 TeV, making this the highest-energy gamma-ray source catalog to date. We report the integral flux of each of these objects. We also report spectra for three highest-energy sources and discuss the possibility that they are PeVatrons.
我们利用高海拔水切伦科夫天文台的数据，展示了首个能量高于56 TeV和100 TeV的伽马射线源目录。该天文台具有宽广的视场，能够探测高达数百TeV的伽马射线。在56 TeV以上观测到了9个源，它们都可能起源于银河系。有3个源在超过100 TeV后仍在发射，这使得该目录成为迄今为止能量最高的伽马射线源目录。我们报告了这些天体各自的积分通量。我们还报告了三个能量最高的源的光谱，并讨论了它们是拍电子伏伽马射线源的可能性。
