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…
A Python/CuPy Software Correlator for QUEST: Real-Time Performance and Initial Imaging
Jialang Ding, Guanhong Lin, Dejia Zhou +20
We present a Python/CuPy FX software correlator for small radio interferometer arrays and evaluate it on QUEST (Qilu University Explorer Survey Telescope). The system combines mult…
Towards the Giant Radio Array for Neutrino Detection (GRAND): the GRANDProto300 and GRAND@Auger prototypes
GRAND Collaboration, Jaime Ãlvarez-Muniz, Rafael Alves Batista +118
The Giant Radio Array for Neutrino Detection (GRAND) is a proposed multi-messenger observatory of Ultra-High-Energy (UHE) particles of cosmic origin. Its main goal is to find the l…
X-ray Binaries: a potential dominant contributor to the cosmic ray spectral knee structure
Hua Yue, Jianli Zhang, Yuhai Ge +5
``PeVatrons" refer to astrophysical sources capable of accelerating particles to energies PeV and higher, potentially contributing to the cosmic ray spectrum in the knee regi…
ASTROFLOW: A Real-Time End-to-End Pipeline for Radio Single-Pulse Searches
Guanhong Lin, Dejia Zhou, Jianli Zhang +20
Fast radio bursts (FRBs) are extremely bright, millisecond duration cosmic transients of unknown origin. The growing number of wide-field and high-time-resolution radio surveys, pa…
A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane
Zhen Cao, Felix Aharonian, Yunxiang Bai +312
Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), γ-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by γ-ray telescopes…
