Thermodynamics, topology and non-Abelian instability of the five-dimensional Einstein--Yang--Mills black hole with exponential entropy correction
Aram Bahroz Brzo, Peshwaz Abdulkareem Abdoul, Behnam Pourhassan +1
The five-dimensional Einstein--Yang--Mills black hole obtained from the higher-dimensional Wu--Yang ansatz carries a logarithmic non-Abelian contribution to the metric function, ma…
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…
Quantum-corrected thermodynamics of Schwarzschild AdS black holes in conformal Killing gravity
Saheb Soroushfar, Sayyed Mehrab Ramezani, Hoda Farahani +2
We study Schwarzschild--AdS black holes in conformal Killing gravity with non-perturbative entropy corrections within the extended phase-space formalism. By deriving the quantum-co…
Gravitational Wave Signatures of Periodic Orbits around a Schwarzschild-like Black Holes Submerged in an Exponential Density Dark Matter Profile
Mohammad Reza Alipour, Saeed Noori Gashti, Mohammad Ali S. Afshar +1
We study a Schwarzschild-like black hole embedded in an exponential-sphere (ESM) dark matter halo, characterized by a halo mass and a scale radius . We first show that t…
Periodic Orbits and Gravitational Wave Signatures around the Bonanno--Reuter Regular Black Hole
Mohammad Reza Alipour, Mohammad Ali S. Afshar, Saeed Noori Gashti +2
Timelike geodesics, periodic orbits, and their associated gravitational-wave signatures are examined in the spacetime of a Bonanno--Reuter regular black hole, a geometry arising fr…
Systematic Light Propagation Bias from the Heliosphere and Its Impact on the Hubble Tension
Behnam Pourhassan, İzzet Sakallı, Sudhaker Upadhyay +1
The Hubble tension (HT) represents one of the most significant discrepancies in modern cosmology, with local distance measurements yielding km/s/Mpc while cosm…
