      𝛾-rays: blazar: core dominance parameter.

    • Abstract

       

      In this paper, we compiled 572 blazars that have known core dominance parameter (log 𝑅), out of which 121 blazars are 𝛾-ray loud blazars. We compared log 𝑅 between 121 blazars and the rest with non 𝛾-ray detections, and found that 𝛾-ray loud blazars showed a different distribution, and their average value of log 𝑅 is greater than that for non 𝛾-ray blazars. Our analysis suggests that the 𝛾-ray emissions are strongly beamed.

    • Continuous Article Publication

      Posted on January 27, 2016

      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.
