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…
