Is quasar variability regulated by the close environment of accretion?
Liang Wu, Jun-Xian Wang, Wen-Ke Ren +1
UV/optical variability in quasars is a well-observed phenomenon, yet its primeval origins remain unclear. This study investigates whether the accretion disk turbulence, which is re…
A surprising excess of radio emission in extremely stable quasars: a unique clue to jet launching?
Wen-Yong Kang, Jun-Xian Wang, Zhen-Yi Cai +6
Quasars are generally divided into jetted radio-loud and non-jetted radio-quiet ones, but why only 10% quasars are radio loud has been puzzling for decades. Other than jet-induced-…
The Relation between X-ray and Ultraviolet Variability of Quasars
Hao Sou, Jun-Xian Wang, Zhang-Liang Xie +2
The relation between X-ray and UV/optical variability in AGNs has been explored in many individual sources, however a large sample study is yet absent. Through matching the XMM-New…
Exploring the Connection between UV/Optical Variations and Radio Emission in Radio-Quiet Quasars: Clues on Radio Emission Origin
Mai Liao, Junxian Wang, Wenyong Kang +1
The radio emission in radio-quiet quasars (RQQs) has been a long mystery and its physical origin remains unclear. In a previous work we find UV/optical more variable quasars have s…
ExoClock project II: A large-scale integrated study with 180 updated exoplanet ephemerides
A. Kokori, A. Tsiaras, B. Edwards +102
The ExoClock project is an inclusive, integrated, and interactive platform that was developed to monitor the ephemerides of the Ariel targets to increase the mission efficiency. Th…
More variable quasars have stronger emission lines
Wen-Yong Kang, Jun-Xian Wang, Zhen-Yi Cai +1
The UV/optical variation, likely driven by accretion disc turbulence, is a defining characteristic of type 1 active galactic nuclei (AGNs) and quasars. In this work we investigate…
