Quantum-Corrected Black Holes in Higher Dimensions: From Gravitational Collapse to Remnants, WGC-Like Behavior and Accretion Signatures

Saeed Noori Gashti, Umair Anwar, Abdul Jawad +4

We study the gravitational collapse of a homogeneous dust sphere in higher-dimensional spacetime, with the loop quantum gravity correction entered through a modified Friedmann equa…

Thermodynamics and optical aspects of ModMax black holes in higher order curvature gravity with quintessence dark energy

Ahmad Al-Badawi, Usman Zafar, Abdul Jawad +1

In this work, we derive an exact black hole solution in higher-order curvature gravity by coupling an electromagnetic sector formulated within the ModMax framework to a quintessenc…

Thermodynamic Topology and Photon Spheres Analysis of Black Holes in Brane-World: Insights from Barrow Entropy

Usman Zafar, Abdul Jawad, Kazuharu Bamba +4

We explore the thermodynamics and geothermodynamics of black holes with Barrow entropy in a brane-world scenario, where the horizon geometry of the black hole is regarded as a frac…
