Fragility of stealth solutions in mimetic gravity
Alireza Allahyari, Clarisse Donio, Mohammad Ali Gorji +2
We study a broad class of constrained mimetic-type extensions of general relativity with action , where i…
Constraining Cubic Curvature Corrections to General Relativity with Quasi-Periodic Oscillations
Alireza Allahyari, Liang Ma, Shinji Mukohyama +1
We investigate observational constraints on cubic curvature corrections to general relativity by analyzing quasi-periodic oscillations (QPOs) in accreting black hole systems. In pa…
Testing loop quantum gravity by quasi-periodic oscillations: rotating blackholes
Jafar Khodagholizadeh, Ghadir Jafari, Alireza Allahyari +1
We investigate a compelling model of a rotating black hole that is deformed by the effects of loop quantum gravity (LQG). We present a simplified metric and explore two distinct ge…
Probing the warped vacuum geometry around a Kerr black hole by quasi-periodic oscillations
M. Hossein Hesamolhokama, Alireza Allahyari, Jafar Khodagholizadeh +1
We investigate quasi-periodic oscillations (QPOs) in the context of a new rotating black hole solution that incorporates a cosmological constant. Recent work by the authors in \cit…
