Rapid Variability and Broadband Spectral Modeling in the Flaring Activity of BL Lacertae

Xin Chang, Dingrong Xiong, Chenxu Liu +17

We report a multi-wavelength study of two flaring episodes of the blazar BL Lacertae during MJD 60500-60800 (9 July 2024 - 5 May 2025). The source reached a daily-averaged -ray…

A Roadmap for Transient Hunters: Mapping Stellar Mass and Star Formation Rate Anisotropies in the Local Universe

Ye-Hao Cheng, Yuan-Pei Yang, Ye Li

Over the past few decades, an increasing number of transients in nearby galaxies have been discovered through various survey projects. Unlike astrophysical phenomena at cosmologica…

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…

A fast powerful X-ray transient from possible tidal disruption of a white dwarf

Dongyue Li, Wenda Zhang, Jun Yang +97

Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…

Spectral Hardening Reveals Afterglow Emergence in Long-Duration Fast X-ray Transients: A Case Study of GRB 250404A/EP250404a

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…

The soft X-ray transient EP241021a: A cosmic explosion with a complex off-axis jet and cocoon from a massive progenitor

Giulia Gianfagna, Luigi Piro, Gabriele Bruni +22

X-ray flashes (XRFs) are fast X-ray transients thought to be softer analogs of gamma-ray bursts (GRBs). With its soft X-ray sensitivity, the Einstein Probe (EP) provides a unique o…

Multiwavelength Analysis of GRB 250101A: From Gamma-ray Prompt Emission to Optical Afterglow

Guowang Du, Yehao Cheng, Yuan-Pei Yang +15

The interaction between the relativistic jet and the circumburst medium produces a multiwavelength afterglow of a gamma-ray burst (GRBs). In this work, we present multiwavelength p…

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…

Multiband Simultaneous Photometry of Type II SN 2023ixf with Mephisto and the Twin 50-cm Telescopes

Yuan-Pei Yang, Xiangkun Liu, Yu Pan +13

SN 2023ixf, recently reported in the nearby galaxy M101 at a distance of , was one of the closest and brightest core-collapse supernovae (CCSNe) in the last decade.…
