Probing Lorentz Invariance Violation in Cosmogenic Neutrino Propagation with KM3-230213A

Rodrigo Sasse, Rodrigo Guedes Lang, Rita de Cássia dos Anjos

We investigate superluminal Lorentz invariance violation (LIV) in the neutrino sector using cosmogenic neutrino fluxes generated with ultrahigh-energy cosmic-ray propagation models…

Hadronic origin of gamma rays and neutrinos from blazars: Multi-messenger implications and observational constraints

Rodrigo Sasse, Rita de Cássia dos Anjos

We investigate whether cosmogenic gamma rays and neutrinos from ultra-high-energy cosmic rays (UHECRs) produced in hadronically active blazars can significantly contribute to the o…

The Roche-Lobe Radius in Newtonian and Non-Newtonian Gravity

A. M. Velasquez-Toribio

In this paper, we extend the standard calculation of the Roche lobe from the Newtonian potential to non-Newtonian models, specifically Yukawa-type and power-law potentials. These m…

A rotating black hole in a Hernquist dark matter halo: horizon geometry, thermodynamics, and quantum emission

A. A. Araújo Filho, Arun Kumar, N. Heidari +3

We investigate the geometrical, thermodynamic, and quantum emission properties of a rotating black hole immersed in a Hernquist dark matter halo. Starting from a static black hole…

Non-thermal emission from the vicinity of the magnetar CXOU J171405.7-381031

Manoel F. Sousa, Rita. C. Anjos

Magnetars are neutron stars with ultra-strong magnetic fields (- G) and are promising candidates for high-energy particle acceleration. We present a multiw…

Multiwavelength study of non-thermal emission in the Swift J1834.9-0846/W41 region

Manoel F. Sousa, Rita C. Dos Anjos, Vitor de Souza

We investigate the origin of non-thermal emission from the Swift J1834-0846/W41 region by modeling its broadband spectral energy distribution from radio to TeV energies within lept…
