最近发现的黑洞候选者GRO J1655-40是研究黑洞周围吸积盘物质喷流的理想系统。对射电辐射的观测显示，两个高度准直的相对论性喷流，分别位于源的两侧，它们在几天内膨胀和衰减。喷流的喷射速度为光速的92%，呈现出不对称的现象;喷流的交替变亮和变暗不能用相对论性光束解释。
GRO J1655-40, a recently discovered black-hole candidate, is an ideal system for studying jets of material from the accretion disk around a black hole. Observations of the radio emission show two highly collimated relativistic jets, one on each side of the source, which expand and decay over a few days. The jet ejection, at 92% of the speed of light, appears episodic and asymmetric; the alternate brightening and fading of the jets cannot be explained by relativistic beaming.
