A research team led by Professor Wang Tao from Nanjing University used the Webb Space Telescope and ALMA to observe a cold gas 'ram pressure stripping' event in a galaxy cluster about 11 billion years ago, advancing the known timeline of galaxy quenching by nearly 5 billion years. The findings were published in Nature Astronomy.

南京大学王涛教授团队借助韦布空间望远镜、ALMA望远镜,观测到约110亿年前的星系团冷气体“冲压剥离”事件,将已知星系团中的星系“熄灭”时间提前近50亿年。相关研究成果6月22日发表于《自然·天文学》。<br> 该研究表明,年轻星系团核心的高密度炽热气体便可作用于团内星系冷气体,使其停止生成新恒星,星系团无需成熟或衰老就能抑制恒星形成。<br> (科技日报 潘宇菲 赵卫华)5369152026-06-24 22:40:51:251潘宇菲 赵卫华时间提前近50亿年 天文学家观测到110亿年前星系“熄灭”1324滚动滚动<br> https://www.stdaily.com/web/gdxw/pic/2026-06/24/536915_5f67d8ff-b65c-4194-8e47-fd3962c106a1.png<br> https://www.stdaily.com/web/gdxw/pic/2026-06/24/536915_5f67d8ff-b65c-4194-8e47-fd3962c106a1.png<br> https://www.stdaily.com/web/gdxw/pic/2026-06/24/536915_5f67d8ff-b65c-4194-8e47-fd3962c106a1.png<br> https://www.stdaily.com/web/gdxw/pic/2026-06/24/536915_5f67d8ff-b65c-4194-8e47-fd3962c106a1.pnghttps://www.stdaily.com/web/gdxw/2026-06/24/content_536915.htmlnull科技日报100/enpproperty-->
