Measurement of Cosmic-Ray Density in the Spiral Arms toward Galactic Anticenter

Jia-hao Liu, Bing Liu, Rui-zhi Yang

Using nearly 17 years of Fermi-LAT data, we analyzed the diffuse gamma-ray emission associated with different spiral arms of the Milky Way in the ranges to $145^\ci…

Superdiffusion of cosmic rays in the vicinity of their accelerators and the resulting -ray emission

Zhaodong Shi, Guangwei Wang, Rui-zhi Yang

We study the distribution of cosmic rays (CRs) in the vicinity of their accelerators, assuming that the transport of CRs in the interstellar medium surrounding the accelerators is…

Extreme Transients in Gamma Rays

Daniela Hadasch, Dmitriy Khangulyan

Extreme gamma-ray transients represent some of the most energetic and physically constraining phenomena in high-energy astrophysics. They are characterized by rapid, large-amplitud…

Outlier detection in mixed-attribute data: a semi-supervised approach with fuzzy approximations and relative entropy

Baiyang Chen, Zhong Yuan, Zheng Liu +4

Outlier detection is a critical task in data mining, aimed at identifying objects that significantly deviate from the norm. Semi-supervised methods improve detection performance by…

A mechanism-independent methodology for modeling γ-ray phaseograms of pulsars in the framework of north-south symmetry

Paul K. H. Yeung, Dmitry Khangulyan, Takayuki Saito

Fermi-LAT observations revealed that each GeV phase-folded light-curve (aka. phaseogram) of the Crab, Geminga, Dragonfly and Vela pulsars consists of two pulses (P1 & P2) and a "Br…
