MeerKAT discovery of a double radio relic and odd radio circle: connecting cluster and galaxy merger shocks
Bärbel S. Koribalski, Angie Veronica, Klaus Dolag +11
We present the serendipitous discovery of (1) a large double radio relic associated with the galaxy cluster PSZ2 G277.93+12.34 and (2) a new odd radio circle, ORC J1027-4422, both…
The NuSTAR and Chandra view of CL 0217+70 and Its Tell-Tale Radio Halo
Ayşegül Tümer, Daniel R. Wik, Xiaoyuan Zhang +11
Mergers of galaxy clusters are the most energetic events in the universe, driving shock and cold fronts, generating turbulence, and accelerating particles that create radio halos a…
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…
Multi-color optical monitoring of ten blazars from 2005 to 2011
Nankun Meng, Xiaoyuan Zhang, Jianghua Wu +2
We carried out multi-color optical monitoring of a sample of ten blazars from 2005 to 2011. The sample contains 3 LBLs, 2 IBLs, 4 HBLs, and 1 FSRQ. Our monitoring focused on the lo…
Intra-day optical multi-band quasi-simultaneous observation of BL Lacertae object S5 0716+714 from 2013 to 2016
Xiaoyuan Zhang, Jianghua Wu, Nankun Meng
We perform quasi-simultaneous optical multi-band monitoring of BL Lac object S5 0716+714 on seven nights from 2013 to 2016. Intra-day variability (IDV) is found on all seven nights…
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…
Simultaneous optical monitoring of BL Lacertae object S5 0716+714 with high temporal resolution
Zhongyi Man, Xiaoyuan Zhang, Jianghua Wu +1
We have monitored the BL Lacertae object S5 0716+714 simultaneously in the B, R and I bands on three nights in November 2014. The average time resolution is quite high (73s, 34s, 5…
Six-year Optical Monitoring of BL Lacertae Object 1ES 0806+52.4
Zhongyi Man, Xiaoyuan Zhang, Jianghua Wu +2
We present the results of the first systematic long-term multi-color optical monitoring of the BL Lacertae object 1ES 0806+52.4. The monitoring was performed in multiple passbands…
