Using 𝛾-ray band data detected by Fermi Large Area Telescope (LAT) and X-ray band data for 78 blazars, we find a medium correlation between X-ray and 𝛾-ray fluxes in the average state. A medium anticorrelation is also found between X-ray (1 KeV) mean spectral index 𝛼𝑥 and 𝛾-ray mean spectral index 𝛼𝛾 for blazars. Our results suggest that the most likely radiation mechanism for the high energy 𝛾-ray would be SSC. And that the 𝛾-ray emission mechanism may be somewhat different for BL Lacs and FSRQs.

Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
