Particle Dynamics and Quasi-Periodic Oscillations in the GUP-Modified Schwarzschild Spacetime: Constraint Using Micro-Quasars Data

Husanboy Hoshimov, Odil Yunusov, Farruh Atamurotov +2

In this work, we have worked out dynamical aspects for the particles moving around the GUP-corrected-Schwarzschild (S-GUP) black hole. We have calculated the innermost stable circu…

Constraints on Metric-Palatini Gravity from QPO Data

Elham Ghorani, Samik Mitra, Javlon Rayimbaev +4

In this work, we study metric-Palatini gravity extended by the antisymmetric part of the affine curvature. This gravity theory leads to general relativity plus a geometric Proca fi…
