Time Evolution of Optical Darkness in GRB Afterglow: The Case of GRB 240825A
Rui-Zhi Li, Jirong Mao, Yuan-Pei Yang +4
Long-duration gamma-ray bursts (GRBs) are believed to occur in star-forming regions. The multiwavelength follow-up observations of the early afterglow of GRB 240825A provided insig…

On the Detection and Characterization of Quasiperiodic Oscillations in Astronomical Time Series: Gamma-Ray Burst X-Ray Light Curves as a Test Case
Fei-Fan Song, Jirong Mao
The study of temporal properties of variable sources can elucidate their physical processes. In this context, we present a critical study comparing three approaches to periodic or…
