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…

Dynamical chiral symmetry breaking in rotating QED: critical flavor number and the occupation-reweighting channel

Wei Li

We study dynamical chiral symmetry breaking in -dimensional QED on a rigidly rotating disc, , within the rainbow Schwinger--Dyson framework. At zero temperature the…

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…

Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd

Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38

We present multi-wavelength observations of the tidal disruption event (TDE) 2024aepd, spanning primarily the first 300 days after discovery. A prominent near-infrared (NIR)…

X-rays breaking out of pre-explosion ejecta mark a supernova's first light

Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130

Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…

The Intermediate-Mass Black Hole Reverberation Mapping Project: Stable Optical Continuum Lags of an IMBH in the Dwarf Galaxy NGC 4395 Over Years

Yu Pan, Hengxiao Guo, Chenxu Liu +15

NGC 4395 is a nearby dwarf spiral galaxy hosting an active galactic nucleus (AGN) powered by an intermediate-mass black hole (IMBH, --). Re…
