Based on the 31 high redshift (𝑧 > 2) Flat Spectral Radio Quasars (FSRQs), which is from the second Fermi-LAT AGNs catalogue (2LAC), we studied the correlation between flux densities (𝐹R, 𝐹K, 𝐹𝛾) in the radio, infrared and 𝛾-ray wave bands. We found that there is a significant positive correlation between 𝐹𝛾 and 𝐹R, and a weak anticorrelation between 𝐹𝛾 and 𝐹K in the average state. For high redshift blazars, we argue that the seed photon of 𝛾-ray emission mainly comes from the jet itself and partially from the dusty torus.

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.
