摘要
我们表明，gamma射线谱线在约0.4 Mev和<=0.2 Mev处可以通过Galactic黑洞候选者喷流中beamed辐射的Compton散射产生。该机制的新颖之处在于不涉及--成对的存在。为产生这两条谱线，我们采用约0.5c的对称双面喷流，并使用硬能量谱的入射beamed辐射。我们表明，对于视角余弦范围在0.2到0.6之间(占总固角的40%)都可以看到这两条谱线。此外，谱线辐射约为10%偏振。 Depending on the bulk flow and viewing angle, the model can produce lines at other energies as well. In particular a broad feature near 1 MeV can be seen by viewing the jet close to its axis. Our model can also accommodate single line spectra if the beamed gamma ray emission or the jets themselves are asymmetric.
