高海拔水切伦科夫（HAWC）伽马射线天文台是一个宽视场天文台，对500 GeV-100 TeV伽马射线和宇宙射线敏感。HAWC天文台每天观测超过2/3的天空，对各种各样的天体物理来源非常敏感，包括可能来自暗物质的伽马射线。银河系中的暗物质湮灭和衰变应该会在天空中产生许多度的伽马射线信号。HAWC的瞬时视场为2 sr，可以观测天空中的扩展区域，例如银河系晕中的暗物质。在这里，我们显示了限制暗物质湮灭截面和衰变寿命HAWC观测银河系晕15个月的数据。这些是对TeV和PeV暗物质的一些最强大的限制，对暗物质形态基本不敏感。这些限制开始约束模型，在该模型中，PeV冰立方中微子被解释为主要衰变为强子的暗物质。
The High Altitude Water Cherenkov (HAWC) gamma-ray observatory is a wide field-of-view observatory sensitive to 500 GeV–100 TeV gamma rays and cosmic rays. With its observations over 2/3 of the sky every day, the HAWC observatory is sensitive to a wide variety of astrophysical sources, including possible gamma rays from dark matter. Dark matter annihilation and decay in the Milky Way Galaxy should produce gamma-ray signals across many degrees on the sky. The HAWC instantaneous field-of-view of 2 sr enables observations of extended regions on the sky, such as those from dark matter in the Galactic halo. Here we show limits on the dark matter annihilation cross-section and decay lifetime from HAWC observations of the Galactic halo with 15 months of data. These are some of the most robust limits on TeV and PeV dark matter, largely insensitive to the dark matter morphology. These limits begin to constrain models in which PeV IceCube neutrinos are explained by dark matter which primarily decays into hadrons.
