Blazar成协高能中微子的研究

Blazar是一类特殊的活动星系核，其电磁辐射从低能射电一直延伸到高能的伽玛射线，它一直是天体物理领域最活跃的研究领域之一。近期，IceCube探测到与Blazar耀发期间成协的中微子事件给我们提供了独特的研究契机。对Blazar中微子的研究有利于我们理解Blazar天体的基本性质，包括中心超大质量黑洞的活动，喷流的性质，辐射机制问题，以及辐射区域问题等等，具有非常重要的意义。该项目将以Blazar中的中微子辐射和多波段的电磁辐射进行研究为基础，进而对以上重要问题进行研究。同时该项目研究也可以帮助对极高能宇宙射线的加速以及宇宙中微子背景的贡献源等进行理解。Blazar成协中微子的发现和研究，将极大地促进中微子天文学和高能天体物理的发展。

Blazar, whose electromagnetic radiation extends from low-energy radio emission to high-energy gamma rays, is a special class of active galaxy cores and has been one of the most active research fields in astrophysics. Recently, IceCube's detection of the neutrino event associated with Blazar's flares provided us with a unique research opportunity. The study of Blazar neutrinos has very important significance and is helpful for us to understand the basic properties of Blazar, including the activity of the central supermassive black hole, the nature of the jet, the radiation mechanism, and the radiation area, etc. The project to study the above important issues will be based on the research of neutrino radiation and multi-wavelength electromagnetic radiation in Blazar. At the same time, the project research can also help to understand the acceleration of very high-energy cosmic rays and the contribution sources of the neutrino background of the universe. The discovery and research of neutrinos associated with Blazar will greatly promote the development of neutrino astronomy and high-energy astrophysics.
