Reconstructing the Auger UHECR Dipole: A Hybrid Analysis of 4LAC AGNs and Nearby Starburst Galaxies

Swaraj Pratim Sarmah, Umananda Dev Goswami, Sovan Chakraborty

The large-scale dipole anisotropy observed by the Pierre Auger Observatory above ~EeV provides important clues about the origin of ultra-high-energy cosmic rays (UHECRs). In thi…

Study of Flat Spectrum Radio Quasars and BL Lacertae Objects as Sources of Diffusive Ultra High-Energy Cosmic Rays

Swaraj Pratim Sarmah, Umananda Dev Goswami

We examine whether Flat Spectrum Radio Quasars (FSRQs) and BL Lacertae objects (BL Lacs) can act as plausible astrophysical sources of diffuse ultra-high-energy cosmic rays (UHECRs…

Propagation of UHE cosmic rays in the light of f(R) gravity power-law model

Swaraj Pratim Sarmah

While the origins of ultra-high energy (UHE) cosmic rays (CRs) remain shrouded in uncertainty, several important milestones have been reached in recent years in the experimental st…

Ultra-high energy cosmic rays with UFA-15 source model in Bumblebee gravity theory

Swaraj Pratim Sarmah. Pranjal Sarmah, Umananda Dev Goswami

We explore the effects of Bumblebee gravity on the propagation of ultra-high energy cosmic rays (UHECRs) using astrophysical sources modelled in the Unger-Farrar-Anchordoqui (UFA)…

Analysing Ultra High Energy Cosmic Rays' Anisotropy in Gravity Theory

Swaraj Pratim Sarmah, Umananda Dev Goswami

In this study, we investigated the anisotropy of diffusive Ultra-High Energy Cosmic Rays (UHECRs) by employing three cosmological models: two models from the gravity theo…

Modelling Cosmic Rays Flux with Pierre Auger and Telescope Array Data in and Theories of Gravity

Swaraj Pratim Sarmah, Umananda Dev Goswami

We investigate the effects of the magnetic field and the redshift on the propagation of galactic and extragalactic cosmic rays (CRs) in a modified theory of gravity (MTG) and an al…
