Correlation Analysis of Broad Band Spectral Indices and Synchrotron Peak of Blazars

Chen Xiang-xin

Open publisher page 0 citations

Abstract

In this thesis,a large sample of 218 blazars was collected,including the observation data from radio to X-ray energy band.The broad band spectral indices αro,αrx and αox were calculated.For HBLs,LBLs and FSRQs,there are negative correlations between the broad band spectral index and synchrotron peak.The correlation between the spectral index and composite spectral index is strong and negative.The αrx vs.αox,are all strongly correlated for all blazars.There is strong correlation of αrx between LBLs and FSRQs.The αrx can be used to classify BL Lacs.
