The sound of quintessence: analogue Kiselev acoustic black holes
Luis C. N. Santos, H. S. Vieira, Franciele M. da Silva +1
In this work, we demonstrate that the geometry of a spherically symmetric black hole surrounded by a Kiselev anisotropic fluid can be effectively mimicked by an experimental setup…
Charged scalar boson in Melvin universe
L. G. Barbosa, L. C. N. Santos, J. V. Zamperlini +2
This work investigates the dynamics of a charged scalar boson in the Melvin universe by solving the Klein-Gordon equation with minimal coupling in both inertial and non-inertial fr…
Strongly Interacting Quark Matter in Massive Quark Stars
Adamu Issifu, Franciele M. da Silva, Luis C. N. Santos +2
This paper investigates the properties of strongly coupled matter at high baryon densities (\(Ï_B\)) in quark stars (QSs). The QS model is based on the density-dependent quark mas…
Black holes as gravitational mirrors
L. C. N. Santos, F. M. da Silva, C. R. Muniz +1
Retrolensing is a gravitational lensing effect in which light emitted by a background source is deflected by a black hole and redirected toward the observer after undergoing nearly…
Constraining the Generalized Tolman-Oppenheimer-Volkoff (GTOV) equation with Bayesian analysis
Franciele M. da Silva, Fábio Köpp, Marcelo D. Alloy +4
In this work, we constrain the values of the parameters of the Generalized Tolman-Oppenheimer-Volkoff (GTOV) equation through Bayesian inference. We use the mass and radius data fr…
Cornell and Coulomb potentials in the double defect spacetime
L. G. Barbosa, L. C. N. Santos, J. V. Zamperlini +1
We analyze the quantum dynamics of a scalar field in a spacetime incorporating dual topological defects, specifically a cosmic string and a global monopole. Utilizing a generalized…
