Swampland diagnostics and observational tests of the inflationary universe in the Palatini formalism
Saeed Noori Gashti, Mohammad Reza Alipour, Mohammad Ali S. Afshar +1
We consider quintessential inflation in a quadratic Palatini model with a generalized Peebles-Vilenkin potential, where the same scalar field describes both the inflationary platea…
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…
Geometry-Induced Termination of the Repetitive Penrose Process in Rotating Simpson-Visser Black Holes
Mohammad Ali S. Afshar, Mohammad Reza Alipour, Saeed Noori Gashti +1
We examine the Repetitive Penrose Process in the rotating Simpson-Visser spacetime, whose parameter space includes regular black holes, black-bounce geometries, and traversable wor…
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…
Repetitive Penrose Process in Rotating 4D Einstein-Gauss-Bonnet Black Holes
Mohammad Reza Alipour, Mohammad Ali S. Afshar, Saeed Noori Gashti
We investigate the repetitive Penrose process for neutral particles in a rotating four-dimensional Einstein--Gauss--Bonnet black hole obtained through the modified Newman--Janis al…
Repetitive Penrose process for charged particles in Kerr-Newman black holes
Mohammad Reza Alipour, Saeed Noori Gashti, Mohammad Ali S. Afshar
We investigate the repetitive Penrose process for charged particles in an initially extremal Kerr--Newman black hole and develop a nonlinear iterative framework in which the black-…
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…
Testing the Weak Gravity Conjecture via Gravitational Lensing, Black Hole Shadows, and Barrow Thermodynamics in F(R)-Euler-Heisenberg (A)dS Black Holes
Saeed Noori Gashti, Izzet Sakalli, Erdem Sucu +5
We investigate the interplay of the Weak Gravity Conjecture (WGC) and the Weak Cosmic Censorship Conjecture (WCCC) in -Euler-Heisenberg black holes in Anti-de Sitter and de S…
Holographic CFT Phase Transitions and Criticality for Einstein-Maxwell-Power-Yang-Mills AdS Black Holes
Mohammad Reza Alipour, Mohammad Ali S. Afshar, Saeed Noori Gashti +1
We present a comprehensive study of the thermodynamic phase structure for Anti-de Sitter black holes in Einstein-Maxwell-power-Yang-Mills gravity, reformulated through holographic…
