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…

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…

Can wormhole spacetimes in Unimodular Gravity be supported by ordinary matter? A general proof of the exotic matter requirement

Mauricio Cataldo, Norman Cruz, Patricio Salgado

We establish a general no--go theorem demonstrating that all traversable wormhole configurations in Unimodular Gravity necessarily require exotic matter. The proof relies solely on…
