关于超光速源的洛伦兹因子
On the Lorentz Factor of Superluminal Sources
摘要:
我们调查的特性的超光速源内看到的功能通常被称为组件。我们的研究结果表明,在我们的样本中,类星体的r=0.6,星系的r=0.4,BL Lac天体的r=0.8之间的组件大小和距离固定的核心相当强的相关性。自由绝热膨胀等离子体的假设使我们能够在一般情况下限制超光速源的洛伦兹因子。估计类星体的洛伦兹因子为7 - 17,星系为6 - 13,BL Lac天体为4- 9,表明BL Lac天体的洛伦兹因子范围最小。
英文摘要:
We investigate the properties of features seen within superluminal sources often referred to as components. Our result indicates a fairly strong correlation of r=0.6 for quasars, r=0.4 for galaxies, and r=0.8 for BL Lac objects in our sample between component sizes and distances from the stationary core. Assumption of free adiabatic expanding plasma enabled us to constrain in general the Lorentz factor for superluminal sources. Ourestimated Lorentz factor of 7 - 17 for quasars, 6 - 13 for galaxies and 4- 9 for BL Lac objects indicate that BL Lac have the lowest range of Lorentz factor.
