关于位于我们银河系中心人马座A* (Sgr A*)的致密非热射电源的能量来源，最好的假设是附近发光恒星发出的风对一个大质量黑洞的吸积。黑洞的质量、吸积速率和被吸积物质的最终命运都是不确定的。在本报告中，我总结了最近的批评意见。对这些结果的解释支持这一一般假设，并开始对模型参数施加约束。如果是这样，那么Sgr A*就是处于静止状态的星系外agn的缩小版。
The best hypothesis for the energy source of the compact, nonthermal radio source in the center of our galaxy, Sagittarius A* (Sgr A*), is accretion onto a massive black hole from winds emanating from nearby luminous stars. The hole mass, accretion rate, and ultimate fate of accreted matter are uncertain. In this report I give a summary of recent critical observations. The interpretation of these results supports this general hypothesis, and begins to place constraints on model parameters. If so, then Sgr A* is a miniature version of extragalactic AGNs in a quiescent state.
