| 摘 要： | 同步加速辐射是活动星系核低能辐射的主要辐射机制。研究喷流内粒子的同步加速辐射过程对认识活动星系核内部辐射机制,能谱分布、光变时标等热点问题非常重要。文章研究活动星系核喷流内粒子的同步辐射过程,用数值的方法得到喷流内粒子的同步辐射谱分布情况,用得到的粒子谱分布计算了BL Lac天体PKS 2155-304低能辐射。结果表明,PKS 2155-304低能辐射能用同步辐射很好地解释。

| Abstract: | Synchrotron radiation is the active galactic nuclei low-energy radiation from the main radiation mechanism. Research on Particle jet radiation accelerated the process of synchronization of active galactic nuclei understanding the mechanism of internal radiation, spectrum distribution, optical variable hot-spot issues such as time scale is very important. In this paper, active galactic nuclei jet synchrotron radiation in the process of particles, using numerical methods of particle jet of synchrotron radiation inside the spectral distri- bution of the particle spectra have been used to calculate the distribution of BL Lac objects PKS 2155-304 lowenergy radiation. The results show that, PKS 2155-304 low-energy synchrotron radiation can be explained very well. |
