Signatures of AGN outflows in X-rays

Ultra-fast outflows (UFOs) are highly ionized, mildly relativistic winds seen in the X-ray spectra of active galactic nuclei (AGN) and are thought to contribute to AGN feedback...超高速外流（Ultra-fast outflows, UFOs）是一类在活动星系核（active galactic nuclei, AGN）的X射线光谱中观测到的高度电离、呈轻度相对论性的外流风，且被认为可对活动星系核反馈做出贡献……
