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…
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…
Sources of matter for wormholes in a k-essence theory
Marcos V. de S. Silva, Carlos F. S. Pereira, Bruna Bragato +3
The paper investigates wormhole solutions in a k‑essence theory coupled to a phantom scalar field, deriving the scalar field, potential, and electromagnetic functions for electrica…
Multiwavelength study of non-thermal emission in the Swift J1834.9-0846/W41 region
Manoel F. Sousa, Rita C. Dos Anjos, Vitor de Souza
The paper models the broadband non‑thermal emission from the Swift J1834.9‑0846/W41 region, comparing leptonic and lepto‑hadronic scenarios and finding that a lepto‑hadronic model…
Joint Curvature and Growth Rate measurements with Supernova Peculiar Velocities and the CMB
Camilo Crisman, Miguel Quartin, João Rebouças
Type Ia supernova (SN) magnitudes present correlations due to the fact that their peculiar velocities are sourced by the large-scale structure of the Universe. This effect can be u…
A rotating black hole in a Hernquist dark matter halo: horizon geometry, thermodynamics, and quantum emission
A. A. Araújo Filho, A. A. Araújo Filho, Arun Kumar +4
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…
