X-Ray Binaries: A Potential Dominant Contributor to the Cosmic-Ray Spectral Knee Structure
The Astrophysical Journal“PeVatrons” refer to astrophysical sources capable of accelerating particles to energies of ∼PeV and higher, potentially contributing to the cosmic-ray spectrum in the knee region.

Ultra-High-energy Cosmic Ray Production in Binary Neutron Star Mergers
The Astrophysical Journal LettersHaving previously argued that binary neutron star (BNS) mergers are the principle source of ultra-high-energy cosmic rays (UHECRs), we exploit here the highly constrained initial conditions to make quantitative predictions for the cutoff energy of ...

On Gamma Rays as Predictors of Ultra-high-energy Cosmic-Ray Flux in Active Galactic Nuclei
The Astrophysical JournalActive galactic nuclei (AGN) are among the main candidates for ultra-high-energy cosmic-ray (UHECR) sources. However, while some theoretical and phenomenological works favor AGNs as the main sources, recent works have shown that using the very-high ...

Cosmogenic Origin of KM3-230213A: Delayed Gamma-Ray Emission from a Cosmic-Ray Transient
The Astrophysical Journal LettersThe highest-energy cosmic neutrino detected by the ARCA detector of KM3NeT has reignited the quest to pinpoint the sources of ultrahigh-energy cosmic rays (UHECRs; E ≳ 0.1 EeV).

Acceleration of Ultra-high-energy Cosmic Rays in the Kiloparsec-scale Jets of Nearby Radio Galaxies
The Astrophysical Journal LettersRadio galaxies have long been considered as potential sources of ultra-high-energy cosmic rays (UHECRs). Recent analyses of the UHECR spectrum, composition, and arrival directions indicate that the nearest radio galaxy, Centaurus A, could be linked to ...

Cosmogenic Neutrino Point Source and KM3-230213A
The Astrophysical JournalCosmogenic neutrinos (CNs) are produced by ultra-high-energy cosmic rays (UHECRs) interacting with cosmic background radiation. We investigated the properties of CN point/extended sources, i.e., the neutrino spectrum and angular profile as functions of ...
