Redshift evolution of the Amati relation: calibrated results from the Hubble diagram of quasars at high redshifts
Yan Dai, Xiao-Gang Zheng, Zheng-Xiang Li +2
Gamma-ray bursts (GRBs) have long been proposed as a complementary probe to type Ia supernovae (SNe Ia) and cosmic microwave background to explore the expansion history of the high…
Intra-day variability of BL Lacertae from 2016 to 2018
Tian Li, Jianghua Wu, Nankun Meng +2
We monitored BL Lacertae in the B, V, R and I bands for 14 nights during the period of 2016-2018. The source showed significant intraday variability on 12 nights. We performed colo…
Intraday Optical Variability of BL Lacertae
Nankun Meng, Jianghua Wu, James R. Webb +2
We monitored BL Lacertae simultaneously in the optical B, V, R and I bands for 13 nights during the period 2012-2016. The variations were well correlated in all bands and the sourc…
Seven-Year Multi-Color Optical Monitoring of BL Lacertae Object S5 0716+714
Yan Dai, Jianghua Wu, Zong-Hong Zhu +4
We have monitored the BL Lac object S5 0716+714 in five intermediate optical wavebands from 2004 September to 2011 April. Here we present the data that include 8661 measurements wh…
Color Behavior Of BL Lacertae Object OJ 287 During Optical Outburst
Yan Dai, Jianghua Wu, Zong-Hong Zhu +2
This paper aims to study the color behavior of the BL Lac object OJ 287 during optical outburst. According to the revisit of the data from the OJ-94 monitoring project and the anal…
