Day-timescale Quasi-periodic Oscillations of the Gev BL Lac RX J0805.4+7534 with TESS
Xin-Shun Jin, Ting-Feng Yi, Yangwei Zhang +4
This paper reports for the first time the detection of quasi-periodic oscillations (QPOs) in the light curves of the BL Lacertae object RX J0805.4+7534. The Transiting Exoplanetary…
The Next-Generation 21CMA Telescope: Design, Commissioning, and Instrumental Effects in an SKA-LFAA-Like System
Jun-Hua Gu, Quan Guo, Liang Dong +11
As the Square Kilometre Array (SKA) approaches operational status, its complex digital architecture introduces new instrumental challenges. To explore relevant observational and da…
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…
