亚利桑那州立大学的天文学家发现，超大质量黑洞发出的高能喷流能够影响距离星系中心数十万光年处的气体，通过保持这些气体处于炽热状态并阻止其向内坠落，从而决定星系是否继续形成恒星或进入静默阶段 1。研究人员结合DESI和LOFAR射电望远镜的观测数据，检测到了沿喷流方向的电离氢辐射信号，揭示了黑洞对星系长期演化的深远影响 1。
这项研究表明，圆星系介质（CGM）的延伸范围约为星系可见部分的10-20倍，而喷流的作用范围覆盖这一广袤区域 1。研究人员发现H-alpha信号沿着无线电喷流方向显著增强，为黑洞调控星系命运提供了直接观测证据 1。亚利桑那州立大学的Sanchayeeta Borthakur表示："这是一项开创性成果，解决了黑洞如何影响星系、恒星和我们生命的长期谜团" 1。该研究由NASA、太空望远镜科学研究所和美国国家科学基金会资助，已发表于《天体物理学杂志快报》2026年第1009卷第2期，第L34页 1。
Astronomers at Arizona State University have discovered that high-energy jets emanating from supermassive black holes can influence gas located hundreds of thousands of light-years beyond a galaxy's visible edge.1 By keeping this gas intensely hot and preventing it from collapsing inward, these jets may ultimately determine whether a galaxy continues forming stars or enters a dormant state.1 The researchers combined observational data from the DESI survey and the LOFAR radio telescope to detect ionized hydrogen radiation signals aligned with the jet direction, revealing the profound influence black holes exert on long-term galactic evolution.1
The study, published in The Astrophysical Journal Letters in 2026, Volume 1009, Issue 2, page L34, demonstrates that the circumgalactic medium—the region of gas surrounding galaxies—extends roughly ten to twenty times farther than the visible portions of galaxies themselves.1 Researchers identified a significant enhancement in H-alpha signal intensity along the radio jet direction, providing direct evidence of the black hole's impact.1 The research collaboration included Timothy Heckman from Johns Hopkins University and Tanmay Singh from Arizona State University, with funding support from NASA, the Space Telescope Science Institute, and the National Science Foundation.1 According to Sanchayeeta Borthakur, "This is a groundbreaking finding that resolves a long-standing mystery about how black holes influence galaxies, stars, and our own existence."1
