IXPE 探索黑洞噴流
IXPE Explores a Black Hole Jet

黑洞是如何產生X 射線的？最近，NASA 的 IXPE 衛星獲取的資料大大推動了對這一長期問題的解答。X 射線無法從黑洞中射出，但可以在附近的高能環境中產生，特別是由向外運動的粒子噴流產生。透過觀測從位於 BL Lac 星系中心的超大質量黑洞附近發出的 X 射線光（被稱為 "耀星"），發現這些 X 射線沒有明顯的偏振現象，這是由高能電子而不是質子產生的。在這幅藝術插圖中，一個強大的噴流從環繞黑洞的橙色吸積盤中噴射而出。瞭解宇宙中的高能過程有助於人類瞭解發生在地球上或地球附近的類似過程。 拼湊起來：每日天文之謎
原文：How do black holes create X-rays? Answering this long-standing question was significantly advanced recently with data taken by NASA’s IXPE satellite. X-rays cannot exit a black hole, but they can be created in the energetic environment nearby, in particular by a jet of particles moving outward. By observing X-ray light arriving from near the supermassive black hole at the center of galaxy BL Lac, called a blazar, it was discovered that these X-rays lacked significant polarization, which is expected when created more by energetic electrons than protons. In the featured artistic illustration, a powerful jet is depicted emanating from an orange-colored accretion disk circling the black hole. Understanding highly energetic processes across the universe helps humanity to understand similar processes that occur on or near our Earth. Put it All Together: Astronomy Puzzle of the Day
