耀变体吸积盘与喷流的关联研究
|
摘要
收集了78个耀变体的观测数据,运用线性回归法分析耀变体各个波段之间的相关性,发现宽线区光度和来自喷流的射电、光学、X和伽马4个波段光度之间存在相关性.排除红移的影响,偏相关分析结果同样表明宽线区光度与来自喷流的射电、光学、X和伽马等4个波段的光度之间存在一定的相关性.
A sample of 78 ray-varying samples was collected,and the correlation analysis between the bands was carried out by linear regression method.The luminosity of the wide-line region and the radio,luminosity,X and gamma luminosity from the jet were found.There is a correlation between them.Excluding the effect of redshift,the results of partial correlation analysis also show that there is also a certain correlation between the luminosity of the wide-line region and the luminosity of the four bands of radio,optical,X and gamma from the jet.
