微类星体的高能辐射

High-energy emission from microqusars

Gustavo E. Romero

摘要:

如果微类星体的喷流以相对论性强子的形式携带着巨大的能量,那么伽马射线和中微子就可以通过与喷流外部或内部的物质和光子场的相互作用产生。本文介绍了强子喷注与喷注本身物质、质子和电子的同步辐射产生的光子场以及喷注外部物质(如团簇风)相互作用的计算结果。我简要地讨论了中微子生产在这些情况下和新的伽马射线仪器检测的前景。最后,我对LS I +61 303的性质争议作了一些评论。

英文摘要:

If the jets of microquasars carry a significant power in the form of relativistic hadrons, then gamma rays and neutrinos can be produced by interactions with matter and photon fields either external or internal to the jet. In this paper I present some recent results of calculations of the interaction of hadronic jets with 1) matter of the jet itself, 2) photon fields generated by synchrotron radiation of both protons and electrons, and 3) matter external to the jet (e.g. a clumped wind). I briefly discuss neutrino production in these scenarios and the prospects of detection with new gamma-ray instruments. Finally, I make a few comments on the controversy about the nature of LS I +61 303.
