摘要

中微子观测站的发展引发了多信使天文学的激增。据报道，blazars之间存在多个中微子关联，而中微子产生地点位于其中心（亚）秒差距内。然而，这些进程的性质仍然存在许多问题。下一代事件视界望远镜（ngEHT）在这些研究中处于独特的位置，因为它的高频率和高分辨率可以探测吸积盘区域和秒差距尺度的喷流。这为连接这两个区域以及解开blazars的质子加速和中微子产生开辟了新的机会。我们概述了ngEHT的观察策略，并强调了它对blazars多信使研究的贡献。

Probing Neutrino Production in Blazars by Millimeter VLBI

The advancement of neutrino observatories has sparked a surge in multi-messenger astronomy. Multiple neutrino associations among blazars are reported while neutrino production sites are located within their central (sub)parsecs. Yet, many questions remain on the nature of those processes. The next generation Event Horizon Telescope (ngEHT) is uniquely positioned for these studies, as its high frequency and resolution can probe both the accretion disk region and the parsec-scale jet. This opens up new opportunities for connecting the two regions and unraveling the proton acceleration and neutrino production in blazars. We outline observational strategies for ngEHT and highlight what it can contribute to the multi-messenger study of blazars.
