Testing loop quantum gravity through EHT observations of M87* and Sgr A* using rotating holonomy-corrected black holes
Heena Ali, Sushant G. Ghosh
The Event Horizon Telescope (EHT) has provided a new tool for testing the strong-field regime of gravity by imaging the shadows of M87* and Sgr A*. These observations provide the f…

Parameter estimation of Kerr-Bertotti-Robinson black holes using their shadows
Heena Ali, Sushant G. Ghosh
We investigate the shadow of Kerr-Bertotti-Robinson black holes (KBRBHs), which have a deviation parameter that captures the effect of an external magnetic field on the spaceti…

Shadows and parameter estimation of rotating quantum corrected black holes and constraints from EHT observation of M87* and Sgr A*
Heena Ali, Shafqat Ul Islam, Sushant G. Ghosh
The scarcity of quantum gravity (QG) inspired rotating black holes limits the progress of testing QG through Event Horizon Telescope (EHT) observations. The EHT imaged the supermas…
