All massive galaxies are known to possess super massive black holes (SMBH) in their gravitational centers. When fueled by in-falling gas, these SMBH systems generate huge amounts of radiation across the electromagnetic spectrum and, often, powerful radio jets, forming an active galactic nucleus (AGN). The emitted radiation accelerates powerful AGN winds which interact with gas in the host galaxy. This form of interaction, or AGN feedback, is thought to be a crucial phase in the formation and evolution of galaxies. However, many aspects of the physics of AGN winds remain unanswered. The way to make progress in answering these critical questions is to bring AGN researchers together for an open exchange of ideas. Therefore, the PIs are holding a dedicated conference, “AGN Winds on the Chesapeake'' at the Tidewater Inn, Easton, MD, 11-16 June 2023. The PIs will actively encourage and fund the participation of younger researchers, including post-docs and graduate students, with an emphasis on women and under-represented groups. These young scientists will have the chance to present their results on an equal footing with the most senior researchers in the field.The PIs aim to bring together more than 80 experts and young scientists with the goal of imparting state-of-the-field knowledge to the next generation of AGN researchers. This is of particular importance with the advent of new data from the James Webb Space Telescope, and the imminent launch of a new X-ray observatory, the X-ray Imaging and Spectroscopy Mission. Beyond these missions, the next great observatories, such as LUVOIR and Lynx, will be launched after 2030. Therefore, it is the younger generation of AGN researchers who will be making new advancements with these platforms. The proposed conference will be focused on key astrophysical questions around AGN winds. Among these are: the transfer of material and energy between the black hole and host galaxy; the fundamental parameters of the accretion process fueling the black hole; and the role of radio jets in entrained feedback. The presentations, which will be invaluable for guiding future research, will be disseminated to the greater AGN research community.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

所有的大质量星系都在其引力中心拥有超大质量黑洞（SMBH）。当由下落的气体提供燃料时，这些SMBH系统会产生大量的电磁频谱辐射，并且通常会产生强大的射电喷流，形成活动星系核（AGN）。放射出的辐射加速了强大的活动星系核风，这些风与宿主星系中的气体相互作用。这种形式的相互作用，或AGN反馈，被认为是星系形成和演化的关键阶段。 然而，活动星系核风物理学的许多方面仍然没有答案。在回答这些关键问题方面取得进展的方法是将活动星系核研究人员聚集在一起，公开交换意见。 因此，PI将于2023年6月11日至16日在马里兰州伊斯顿的Tidewater Inn举行专门的会议“切萨皮克上的AGN风”。 PI将积极鼓励和资助年轻研究人员的参与，包括博士后和研究生，重点是妇女和代表性不足的群体。这些年轻的科学家将有机会与该领域最资深的研究人员平等地展示他们的成果。PI旨在汇集80多名专家和年轻科学家，旨在向下一代AGN研究人员传授该领域的知识。 随着詹姆斯·韦伯太空望远镜新数据的出现，以及即将发射的新的X射线观测站-X射线成像和光谱学使命，这一点尤为重要。除了这些任务，下一个伟大的天文台，如LUVOIR和Lynx，将在2030年后发射。因此，年轻一代的AGN研究人员将利用这些平台取得新的进展。 拟议中的会议将集中讨论围绕活动星系核风的关键天体物理问题。其中包括：黑洞和宿主星系之间的物质和能量转移;黑洞加速过程的基本参数;以及无线电喷流在夹带反馈中的作用。 该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
