First Observational Evidence for QPO-like Coevolution between Characteristic Damping Timescales and X-ray Time Lags among AGNs
Haoyang Zhang, Li Zhang
Quasi-periodic oscillations (QPOs) and stochastic variability provide complementary probes of the inner accretion flow around supermassive black holes in active galactic nuclei (AG…

Detection of a puzzling dual-superorbital hard X-ray modulation in the X-ray binary GX 301-2
Haoyang Zhang, Li Zhang
The superorbital modulations (SMs) observed in wind-fed X-ray binaries remain a puzzling phenomenon in astrophysics. To investigate this behavior observationally, we analyzed the l…
