Yi-Han Iris Yin, Yuan Fang, Bin-Bin Zhang +56
The prompt emission and afterglow phases of gamma-ray bursts (GRBs) have been extensively studied, yet the transition between these two phases remains inadequately characterized du…
EP240801a/XRF 240801B: An X-ray Flash Detected by the Einstein Probe and Implications of its Multiband Afterglow
Shuai-Qing Jiang, Dong Xu, Agnes P. C. van Hoof +89
We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on August 1, 2024 by the Einstein Probe (EP) satellite, w…
Stellar occultation observations of (38628) Huya and its satellite: a detailed look into the system
F. L. Rommel, E. Fernández-Valenzuela, B. C. N. Proudfoot +78
The physical and orbital parameters of Trans-Neptunian Objects (TNOs) provide valuable information about the Solar System's formation and evolution. In particular, the characteriza…
