Magnetic rigidity reveals the PeVatron acceleration region in SS 433
Jie Liao, Wancheng Xu, Lang Cui +10
PeVatrons are cosmic accelerators capable of driving particles to petaelectronvolt (PeV) energies. Recently, microquasar jets have emerged as compelling Galactic PeVatron candidate…
FAST Discovery of Jy Radio Pulsations from PSR J2238+5903, Providing a DM Distance Anchor for the Candidate TeV Halo 1LHAASO J2238+5900
Jianli Zhang, Hui Zhu, Guanhong Lin +10
We report the first detection of radio pulsations from PSR J2238+5903, a gamma-ray pulsar spatially coincident with the extended TeV source 1LHAASO J2238+5900. Our 3000 s FAST L-ba…
Searching for Spider-Like Pulsars from TESS Ellipsoidal Lightcurves with X-ray counterparts
Xiaoqing Liang, Partha Sarathi Pal, P. H. Thomas Tam +2
We present a search for new spider pulsar candidates through multi-wavelength cross-matching, including -ray, X-ray, and optical data. A search for sinusoidal-like optical modu…
Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems
The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315
Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…
Unsupervised machine learning classification of gamma-ray bursts based on the rest-frame prompt emission parameters
Si-Yuan Zhu, Lang Shao, Pak-Hin Thomas Tam +1
Gamma-ray bursts (GRBs) are generally believed to originate from two distinct progenitors, compact binary mergers and massive collapsars. Traditional and some recent machine learni…
Identifying Merger-Driven Long Gamma-Ray Bursts based on Machine Learning
Si-Yuan Zhu, Hui-Ying Deng, Fu-Wen Zhang +2
Gamma-ray bursts (GRBs) are classified as Type I GRBs originated from compact binary mergers and Type II GRBs originated from massive collapsars. While Type I GRBs are typically sh…
