GRS 1915+105

GRS 1915+105（或称天鷹座V1487）是由一顆规则恆星和黑洞組成的X射線聯星系，它於1992年8月15日被監視全天的Granat發現。“GRS”缩写自“源自GRANAT（GRANAT source）”，“1915”代表着赤經19時又15分，“105”是指以0.1度為單位的赤緯（也就是赤緯是10.5度）。近紅外線的光譜也證實了此一觀測。這個聯星系統位於天鷹座，距離11,000秒差距。GRS 1915+105是銀河系內已知最重的黑洞，質量約在10至18倍的太陽質量。它也是微類星體，並且這顆黑洞以每秒1,150次的速度高速自轉。 在1994年，GRS 1915+105的噴流成為所知的第一個銀河系內的超光速源。 使用高解析度的電波望遠鏡，如甚大天线阵、MERLIN和甚长基线干涉测量等的觀測设备，顯示出在兩極噴出無線電頻率的同步輻射雙極帶電粒子流。這些研究顯示實際速度約為光速90%的噴流，明顯的有著相對論效應所謂的相對論性畸變超光速運動。 回顧錢卓X射線天文台過去十年的觀測顯示，GRS 1915+105似乎有自我控制成長的機制。噴流噴出的物質不定期的會被由吸積盤吹出的熱風截斷，這陣風剝奪了維持噴流所需要的材料。當風沉寂時，噴流就返回了。 Liu, Q.
