多普勒压缩热力学湮灭辐射的束流模式：对MeV类星变的应用
摘要
热力学湮灭辐射的束流模式比由射电发射活性星系中各向同性非热电子和质子组成的喷流中Compton散射外部各向同性辐射场所产生的束流模式更宽广。因此，蓝移的热力学湮灭辐射可以在观察角度theta > 1/Gamma时（其中Gamma为喷流等离子体的批量洛伦兹因子）为高能辐射光谱的主要贡献。这种效应可能解释了在Compton Gamma Ray Observatory上的Compton望远镜所发现的MeV类星变的光谱特征。 coordinated gamma-ray observations of annihilation line radiation to infer Doppler factors and VLBI radio observations to measure transverse angular speeds of outflowing plasma blobs can be used to determine the Hubble constant. coordinated gamma-ray observations of annihilation line radiation to infer Doppler factors and VLBI radio observations to measure transverse angular speeds of outflowing plasma blobs can be used to determine the Hubble constant.
