Multi-Wave Luminosity of High-Synchrotron-Peaked TeV BL Lacs Detected by Fermi LAT
Dingrong Xiong Xiong Zhang Yonggang Zheng
We have studied the correlations between luminosities (𝐿R, 𝐿IR, 𝐿𝛾) in the radio, near-infrared and 𝛾-ray wave bands for HSP TeV BL Lacs. The results show that there are significant intrinsic correlations between 𝐿R and 𝐿𝛾 and between 𝐿IR and 𝐿𝛾 in all states (high/average/low), and suggest that for HSP TeV BL Lacs, the Synchrotron Self-Compton radiation (SSC) is the main mechanism of high energy 𝛾-ray emission, and the inverse Compton scattering of circum-nuclear dust is likely to be an important complementary mechanism.

Computing Optical Variable Periods of BL Lac Object S5 0716+714 with Period04 Analysis Method
Junping Fu Xiong Zhang Dingrong Xiong
From a large volume of literature, we have collected effective observation of BL Lac object S5 0716+714 in the optical band, and constructed its long-term light curve from 1994 to 2006 AD. The light curve shows that S5 0716+714 is very active and exhibits very complicated non-sinusoidal variations. We used Period04 to analyse the period of light curve variation. Our results show that for S5 0716+714, the long-term period of variation is 3.3 yr which is consistent with the result of Raiter

Debeamed Sequence of LBAS Blazars
Bangrong Huang Xiong Zhang Dingrong Xiong Haojin Zhang
We have collected a sample of 71 𝛾-ray blazars selected from the Fermi LAT Bright AGN Sample (LBAS). The correlation between synchrotron peak luminosities 𝐿p and synchrotron peak frequencies 𝑣p have been studied and there is a weak negative correlation. But after correcting the effect of redshift and Doppler boosting, the relation between intrinsic 𝐿'p and 𝑣'p show significant positive correlation.

Continuous Article Publishing mode
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.
