A Unified Model for the Emission of Supernova-associated Fast X-Ray Transients: Case Studies of EP240414a, EP250108a, and GRB 171205A

Yu-Fei Li, Da-Bin Lin, Jia Ren, Zhi-Lin Chen et autres

Abstract The Einstein Probe (EP) has detected several fast X-ray transients (FXTs) associated with broad-lined Type Ic supernovae (SNe), including EP240414a and EP250108a. The observations reveal common features among these FXTs, but the corresponding physical origin remains debated. By comparing the FXTs …

Modeling the shadow and ring structures of rotating Hayward black holes under magnetic charge and accretion influences

Sen Guo, En‐Wei Liang, Wen-Hao 文浩 Deng 邓, Qing-Quan Jiang et autres

Abstract Building upon our previous work, this study extends the analysis to the rotating case and systematically examines the combined effects of magnetic charge, spin, and accretion flow structure on the resulting shadow and photon ring features. We derive the photon geodesics …

Fast Optical Variability of the TeV Blazar PKS 1725+123 Observed by SVOM-VT and Insights from Multiwavelength Follow-up Observations

Shuo-Yu Liu, Yu-Wei Yu, Ji-Shun Lian, Xin-Ke Hu et autres

Abstract PKS 1725+123 is a flat-spectrum radio quasar (FSRQ) with a redshift of z = 0.586. The detection of this object in the TeV band was reported by the MAGIC telescopes and High Energy Stereoscopic System in 2025 August. Subsequently, we promptly …

Study on the gain stability of resistive THGEM for the HERD transition radiation detector

X.F. Zhang, Huijun Hu, Xiwen Liu, Cong Dai et autres

Abstract The Transition Radiation Detector (TRD) onboard the High Energy cosmic-Radiation Detection (HERD) facility provides accurate energy calibration for the calorimeter (CALO) and serves as an independent gamma-ray burst trigger. Thick Gas Electron Multipliers (THGEMs) are the key elements enabling HERD-TRD to …

Multiwavelength Emission for a Postmerger Magnetar: The Magnetar-driven Poynting Jet and Its Associated Pulsar Wind Nebula

Yun-Peng Li, Da-Bin Lin, Ning-Yuan Zhang, En‐Wei Liang

Abstract A newly born, rapidly rotating magnetar may form in a binary neutron star merger and drive a Poynting flux-dominated relativistic jet. As the jet propagates outward, a forward shock (FS) and a reverse shock (RS) are formed, inflating a pulsar wind …

Shear Particle Acceleration in Structured Gamma-Ray Burst Jets. IV. Thermal versus Nonthermal Emission of the Jet Cocoon

Z. X. Wang, XJ Huang, Hai-Ming Zhang, En‐Wei Liang

Abstract A distinct thermal or quasi-thermal spectral component is occasionally observed in gamma-ray burst (GRB) prompt emission spectra. Taking GRB 090902B as a case study, we investigate its origin within a structured jet framework, in which the outflow consists of an ultrarelativistic …

Polarization signatures of rotating black holes in perfect fluid dark matter spacetimes

Yu-Xiang Huang, Sen Guo, En‐Wei Liang, Kuan Liu et autres

Motivated by horizon-scale polarization observations of M87^{*}, we investigate polarized emission from rotating black holes (BHs) immersed in a perfect fluid dark matter (PFDM) background. Fully relativistic ray tracing is utilized to examine how the polarization structure jointly depends on magnetic-field geometry, …
