摘要：

喷流是吸积过程中无处不在的一部分，从活动星系（AGN）到X射线双星，甚至是新形成的恒星，都可以在各种各样的物体中看到。活动星系核喷流是由其宿主星系的超大质量黑洞通过磁场和流入物质之间的耦合加速的。它们是许多令人兴奋的现象的来源，并且可以深刻地影响较大的星系和周围的星系团。本白皮书指出了新技术可以在该领域取得的进展，重点是将射流加速到相对论速度并准直的区域。ngVLA和新的空间VLBI任务将提供更高的无线电角分辨率、灵敏度和保真度，穿透这一区域寻找更多的物体，并使我们能够解决喷流加速和准直物理学方面的基本问题。在其他波段的干涉测量将使我们能够直接探测耀斑成分。我们还强调需要旋光，这是必不可少的揭示磁场的作用和配置。

英文摘要：

Jets are a ubiquitous part of the accretion process, seen in a wide variety of objects ranging from active galaxies (AGN) to X-ray binary stars and even newly formed stars. AGN jets are accelerated by the supermassive black hole of their host galaxy by a coupling between the magnetic field and inflowing material. They are the source for many exciting phenomena and can profoundly influence the larger galaxy and surrounding cluster. This White Paper points out what advances can be achieved in the field by new technologies, concentrating on the zone where jets are accelerated to relativistic speeds and collimated. The ngVLA and new space VLBI missions will give higher angular resolution, sensitivity and fidelity in the radio, penetrating this zone for additional objects and allowing us to resolve fundamental questions over the physics of jet acceleration and collimation. Interferometry in other bands would allow us to probe directly flaring components. We also emphasize the need for polarimetry, which is essential to revealing the role and configuration of magnetic fields.
