标题： Multi-Wavelength and Multi-Messenger Studies with the next-generation Event Horizon Telescope

摘要： 下一代事件视界望远镜（ngEHT）将为我们提供最佳的机会，在最高的分辨率和灵敏度下研究超大质量黑洞（SMBHs）。与现有的事件视界望远镜（EHT）阵列相比，ngEHT将通过新增站点提高灵敏度和uv覆盖范围，扩大频率覆盖范围（从86 GHz到345 GHz及以上），提供更精细的分辨率（小于15微角秒），并具备更好的监测能力。这将提供一个独特的机会，深入研究围绕SMBH的物理现象，例如吸积盘-喷流联系、产生高能光子和中微子事件的机制、磁场在塑造相对论性喷流中的作用，以及双星SMBH系统的性质。在本白皮书中，我们描述了一些多波长研究和协同作用背景下的ngEHT科学案例。 显示英文摘要

摘要： The next-generation Event Horizon Telescope (ngEHT) will provide us with the best opportunity to investigate supermassive black holes (SMBHs) at the highest possible resolution and sensitivity. With respect to the existing Event Horizon Telescope (EHT) array, the ngEHT will provide increased sensitivity and uv-coverage with the addition of new stations, wider frequency coverage (from 86 GHz to 345 GHz and higher), finer resolution (<15 micro-arcseconds), and better monitoring capabilities. This will offer a unique opportunity to deeply investigate the physics around SMBHs, such as the disk-jet connection, the mechanisms responsible for high-energy photon and neutrino events, the role of magnetic fields in shaping relativistic jets, as well as the nature of binary SMBH systems. In this white paper we describe some ngEHT science cases in the context of multi-wavelength studies and synergies.
