Accelerating electrically charged ModMax black hole solutions in gravity
B. Eslam Panah, N. Heidari, A. Rincón
Using the metric in the context of gravity coupled with the ModMax nonlinear electromagnetic field (the ModMax theory), we derive an exact black hole solution in…
An analytic model for a total process of gravitational collapse: From star to Schwarzschild black hole
Sinya Aoki, Jorge Ovalle
We present an exact analytical model describing a complete gravitational collapse of matter from horizonless initial conditions to black hole formation, tracing the full evolution…
Slowly rotating condensate dark stars beyond the mean-field approximation
Grigoris Panotopoulos, Ángel Rincón, Ilidio Lopes
We investigate rotational properties and universal relations of slowly rotating Bose-Einstein condensate dark stars in the context of General Relativity, both at the mean-field lev…
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…
Shadows of naked singularities and superspinars related to the revisited Kerr-de Sitter spacetimes
Daniel Charbulák, Zdeněk Stuchlík
We construct shadows of superspinars described by the revisited Kerr-de Sitter (rKdS) naked singularity (NS) spacetimes and compare them with those of the standard KdSNS spacetimes…
