GW 250114 ：旋轉黑洞碰撞
GW250114: Rotating Black Holes Collide
發表日期：2025-09-24
這是迄今測量到的最強引力波訊號--它顯示了什麼？ 今年早些時候，位於美國華盛頓和路易斯安那州的鐳射干涉儀引力波天文臺（LIGO）的兩個臂膀都探測到了GW 250114 。 分析表明，該事件是由兩個黑洞（每個黑洞的質量約為太陽質量的 33 倍）凝聚成一個質量約為 63 個太陽質量的更大黑洞時產生的。 儘管該事件發生在大約 10 億光年之外，但訊號卻如此強烈，以至於所有黑洞的自旋以及最終黑洞的初始振鈴都被推斷得異常精確。此外，還比以前更好地證實了之前的預測，即合併黑洞的總事件視介面積大於合併黑洞的事件視介面積。這幅藝術家繪製的插圖描繪了從其中一個黑洞附近看到的碰撞前的想象和概念景象。
原文：It was the strongest gravitational wave signal yet measured -- what did it show? GW250114 was detected by both arms of the Laser Interferometer Gravitational-wave Observatory (LIGO) in Washington and Louisiana USA earlier this year. Analysis showed that the event was created when two black holes, each of mass around 33 times the mass of the Sun, coalesced into one larger black hole with a mass of around 63 solar masses. Even though the event happened about a billion light years away, the signal was so strong that the spin of all black holes, as well as initial ringing of the final black hole, was deduced with exceptional accuracy. Furthermore, it was confirmed better than before, as previously predicted, that the total event horizon area of the combined black hole was greater than those of the merging black holes. Featured, an artist's illustration depicts an imaginative and conceptual view from near one of the black holes before collision.
