论文摘要

重力波事件S190521G - 活动银河核的吸积盘中可能的二进制黑洞合并 - 伴有光学对应物。发光能量释放区域周围的这种密集环境有利于高能$γ$ ray生产。我们使用Fermi-Lat Space $γ$ -Ray theScope的公开数据来报告从候选电磁对应物到S190521G事件的高能$γ$ - 汇款的搜索。找不到明显的信号。我们在100 MeV -300 GEV能量范围内列出了源光谱分布的上限。我们讨论了在宇宙射线加速度,$γ$ -Ray和中微子生产中研究S190521G瞬态的重要性。

The gravitational-wave event S190521g -- a likely binary black hole merger in the accretion disk of an active galactic nucleus -- was accompanied by an optical counterpart. Such dense environments around luminous energy release regions are favourable for high energy $γ$-ray production. We report on a search for high energy $γ$-rays from the direction of the candidate electromagnetic counterpart to the S190521g event using publicly-available data of the Fermi-LAT space $γ$-ray telescope. No significant signal was found. We present upper limits on the spectral energy distribution of the source in the 100 MeV - 300 GeV energy range. We discuss the importance of studying S190521g-like transients in the context of cosmic ray acceleration, $γ$-ray and neutrino production in such sources.
