Radial oscillations of quark stars in light of current astrophysical constraints: A comparative study

G. Panotopoulos, A. Rincon, I. Lopes

We investigate the structural and oscillatory properties of isotropic strange quark stars within General Relativity, focusing on three physically motivated equations of state: the…

Black hole physics within gravity: Quasi-normal spectra and greybody factors

Ángel Rincón, Grigoris Panotopoulos

We investigate several astrophysical motivated properties of a four-dimensional black hole solution in the framework of gravity. The model is characterized by a single addit…

Quasi-normal modes and shadows of scale-dependent regular black holes

Benjamin Koch, Gonzalo J. Olmo, Ali Riahinia +2

In this paper we investigate how a regular scale-dependent black hole, characterized by a single extra parameter , behaves under perturbations by a test field (quasi-normal mod…

Stellar modeling within regularized 4D Einstein-Gauss-Bonnet gravity in light of current astrophysical constraints

G. Panotopoulos, Á. Rincón, I. Lopes

In this study we obtain interior solutions and investigate structural properties of isotropic compact stars in the framework of four-dimensional regularized Einstein-Gauss-Bonnet (…

Quasinormal modes and absorption cross-section of a Bardeen black hole surrounded by perfect fluid dark matter in four dimensions

Ángel Rincón, Sharmanthie Fernando, Grigoris Panotopoulos +1

In this paper we study quasinormal modes and absorption cross sections for the -dimensional Bardeen black hole surrounded by perfect fluid dark matter. Studies of the massle…

Exploring the Structural Properties of Anisotropic Dark Matter-Admixed Quark Stars

G. Panotopoulos, A. Rincón, I. Lopes

We investigate anisotropic compact stars comprising two non-interacting fluids: quark matter and condensed dark matter. Using the MIT Bag model equation of state for quark matter a…
