Comparing Optical Variability of Type 1 and Type 2 AGN from the BAT 9-Month Sample using ASAS-SN and TESS Surveys
Natalie Kovacevic, Xinyu Dai, Heechan Yuk +6
We present an optical variability analysis and comparison of the samples of Seyfert 1 and 2 galaxies, selected from the \textit{Swift} 9-month BAT catalog, using the light curves f…
Optical Monitoring and Long-term Optical Spectral Variability of BL Lacertae Object S5 0716+714
Huai-Zhen Li, Di-Fu Guo, Long-Hua Qin +7
We present photometric observations of the BL Lacertae object S5 0716+714 with a temporal resolution of 120 s in the Sloan i' and r' bands. These observations were conducted using…
Multiwavelength Variability Analysis of the Blazar PKS 0727-11: A 168 Days Quasi-periodic Oscillation in Gamma-ray
Yuncai Shen, Tingfeng Yi, Vinit Dhiman +2
We performed variability analysis of the multiwavelength light curves for the flat-spectrum radio quasar PKS 0727-11. Using the generalized Lomb-Scargle periodogram, we identified…
Two repeated quasi-periodic oscillations in the FSRQ S5 1044+71 observed by TESS
Jun-Jie Wang, Ting-Feng Yi, Yangwei Zhang +4
In this work, we report for the first time two repeated quasi-periodic oscillations (QPOs) in the light curve of the Flat Spectrum Radio Quasar (FSRQ) S5 1044+71. This source was o…
