A Shell Collision Scenario for EP251222b/GRB 251222A: Connecting Prompt Emission and Double-Peaked Afterglow
Run Shi, Di Xiao, Brajesh Kumar +23
GRB 251222A is a long-duration gamma-ray burst at a spectroscopic redshift of . It was detected by the EP as the soft X-ray transient EP251222b before and during the gamma…
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…
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…
Magnetic White Dwarf - M Dwarf Binaries in Pre-mCV Phase as Special Population of Long-Period Radio Transients
Yuan-Pei Yang
Long-period radio transients (LPTs) are a new class of coherent radio sources with periods ranging from minutes to hours. Recently, two LPT sources, ILT J1101+5521 and GLEAM-X J070…
SN 2024aecx: A double-peaked rapidly evolving Type IIb supernova at 11 Mpc
Xingzhu Zou, Brajesh Kumar, Rishabh Singh Teja +28
We present the results of low-resolution spectroscopic and densely sampled multi-band photometric follow-up of supernova (SN) 2024aecx. The SN was discovered in the spiral galaxy N…
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.…
Early-phase simultaneous multiband observations of the Type II supernova SN 2024ggi with Mephisto
Xinlei Chen, Brajesh Kumar, Xinzhong Er +24
We present early-phase good-cadence (hour-to-day) simultaneous multiband ( and bands) imaging of the nearby supernova SN~2024ggi, which exploded in the nearby galaxy, NG…
