Analysing Ultra High Energy Cosmic Rays' Anisotropy in $f (R, T)$ 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 $f (R, T)$ gravity theo…

Magnetic Suppression of Cosmic Rays' Flux in $f (R)$ and $f (Q)$ Theories of Gravity

Swaraj Pratim Sarmah, Umananda Dev Goswami

We investigate the effects of magnetic diffusion on the spectrum of ultra-high energy cosmic rays (UHECRs) from a cosmological perspective. To this end, we consider two modified th…

Galactic dynamics in the presence of scalaron: A perspective from $f (R)$ gravity

Gayatri Mohan, Umananda Dev Goswami

We consider $f (R)$ modified gravity theory incorporating the chameleon mechanism to address galactic dynamics. By employing the metric formalism and utilizing a conformal transform…
