论文摘要

Icecube望远镜从Blazar TXS 0506+056中观察到了与伽马射线的中微子发射。来自Blazar的中微子不得不穿过中央黑洞周围的暗物质(DM)的密集尖峰。这种中微子的观察意味着中微子-DM散射横截面上的新上微边界是DM质量的函数。如果横截面与能量线性呈线性上升,则约束比现有质量的约束要强。对于恒定的横截面,根据DM Spike的详细信息,还可以进行竞争界限。

Neutrino emission in coincidence with gamma rays has been observed from the blazar TXS 0506+056 by the IceCube telescope. Neutrinos from the blazar had to pass through a dense spike of dark matter (DM) surrounding the central black hole. The observation of such a neutrino implies new upper bounds on the neutrino-DM scattering cross section as a function of DM mass. The constraint is stronger than existing ones for a range of DM masses, if the cross section rises linearly with energy. For constant cross sections, competitive bounds are also possible, depending on details of the DM spike.
