STGBD-Net: Spatio-temporal Gradient Basis Decomposition Network for Infrared Small Target Detection
Chen Hu, Mingyu Zhou, Shuai Yuan +4
A key challenge in infrared small target detection (IRSTD) is that weak target signal responses are easily obscured by strong background clutter, frequently resulting in missed det…
Method for testing diffusive shock acceleration and diffusion propagation of 1-100 TeV cosmic electrons with multiwavelength observations of the Geminga halo and pulsar wind nebula
Weikang Gao, Li-Zhuo Bao, Kun Fang +3
Diffusive shock acceleration and diffusion propagation are essential components of the standard cosmic ray model. These theories are based on extensive observations of high-energy…
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…
Joint constraint on the propagation origin of the cosmic-ray spectral knee from energy spectrum and anisotropy observations
Hua Yue, Lin Nie, Yi-Qing Guo +1
The origin mechanism of the cosmic-ray knee region remains an unresolved mystery, with acceleration, interaction, and propagation models drawing significant attention. The latest e…
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…
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…
