卟吩已知最長的黑洞噴流
Porphyrion: The Longest Known Black Hole Jets
發表日期：2024-10-01
黑洞噴流能延伸多遠？最近，我們發現了一個新的記錄：數十億年前活躍的黑洞噴射出了一對長達 2300 萬光年的噴流。 這個令人印象深刻的噴流是由一種通常不會產生長噴流的黑洞產生的，這種黑洞正忙於從下沉氣體中產生輻射。這段動畫影片描述了圍繞這個強大的黑洞系統旋轉時的情景。 畫面中的卟啉是一股快速的高能粒子流，明亮的區域是這些粒子撞擊周圍氣體的地方。這一發現是利用凱克和馬約爾（DESI）光學天文臺以及 LOFAR 和巨型元波射電望遠鏡的資料得出的。 這些噴流的存在表明，黑洞不僅能影響它們的母星系，還能影響到周圍宇宙的更遠處。 你的天空驚喜 1995 年後
原文：How far can black hole jets extend? A new record was found just recently with the discovery of a 23-million light-year long jet pair from a black hole active billions of years ago. Dubbed Porphyrion for a mythological Greek giant, the impressive jets were created by a type of black hole that does not usually create long jets -- one that is busy creating radiation from infalling gas. The featured animated video depicts what it might look like to circle around this powerful black hole system. Porphyrion is shown as a fast stream of energetic particles, and the bright areas are where these particles are impacting surrounding gas. The discovery was made using data from the Keck and Mayall (DESI) optical observatories as well as LOFAR and the Giant Metrewave Radio Telescope. The existence of these jets demonstrates that black holes can affect not only their home galaxies but far out into the surrounding universe.
