SVOM/VT: Instrument Overview, Science Objectives, and First-Year Performance
Yu-Lei Qiu, Li-Ping Xin, Jin-Song Deng +22
The 44-cm Visible Telescope (VT) aboard the Space-based Variable Objects Monitor (SVOM) is a dual-band (400-650 nm and 650-1000 nm) instrument designed to detect and characterize t…
Detection of Oscillations in a Type I X-Ray Burst of 4U 0614+091 with SVOM/ECLAIRs
Sébastien Le Stum, Floriane Cangemi, Alexis Coleiro +29
On 2025 January 10, a thermonuclear (Type I) X-ray burst from the neutron star low-mass X-ray binary \textit{4U~0614+091} was detected with the ECLAIRs instrument on board the \tex…
Minutes-long soft X-ray prompt emission from a compact object merger
An Li, Chen-Wei Wang, Niccolò Passaleva +75
Compact object mergers are multi-messenger sources and known progenitors of some gamma-ray bursts, bright flashes of high-energy radiation powered by a central engine, either an ac…
Simultaneous Multiband Photometry of the Early Optical Afterglow of GRB 240825A with Mephisto
Yehao Cheng, Yu Pan, Yuan-Pei Yang +19
Gamma-ray bursts (GRBs) are the most luminous transients in the universe. The interaction of the relativistic jet with the circumburst medium produces an afterglow and generates mu…
Prompt-to-afterglow transition of optical emission in a long gamma-ray burst consistent with a fireball
Liping Xin, Xuhui Han, Huali Li +19
Long gamma-ray bursts (GRBs), which signify the end-life collapsing of very massive stars, are produced by extremely relativistic jets colliding into circumstellar medium. Huge ene…
