【摘要】：费米伽玛射线空间大区域望远镜(Large Area Telescope,LAT),以前称为Gamma ray Large Area Space Telescope(GLAST))比Energetic Gamma Ray Experiment Telescope(EGRET)提高了观测精度,在服役的初始几个月中已经检测到一些具有快速光变伽玛射线源.用LAT观测结果并结合EGRET观测到的伽玛噪Blazar天体的变化时标和伽玛射线光度来估计天体的中心黑洞质量.我们发现中心黑洞质量下限范围为(0.3～24)×107M⊙,并将此结果与其他作者的研究结果进行了比较,发现结果是一致的.我们也给出了18个有已知超光速伽玛噪Blazar天体的洛伦兹因子(Γ)和视角(θ).
[Abstract]:The large Area Space Telescope (GLAST), formerly known as the Gamma ray large Area Space Telescope (GLAST), has improved the accuracy of observations over the Energetic Gamma Ray experiment Telescope (EGRET), and has detected a number of fast light gamma-ray sources in the first few months of service. The mass of the central black hole of the celestial body is estimated by using the LAT observations combined with the time scale and gamma ray luminosity of the Gamma noise Blazar object observed by EGRET. It is found that the lower mass limit of the central black hole is (0.33 ~ 24) 脳 10 ~ (7) M _ (298), and the results are compared with those of other authors. It is found that the results are in good agreement with those obtained by other authors. We also give the Lorentz factor (螕) and the angle of view (胃) of 18 Blazar objects with known superluminal gamma noise.
