Thanks to the release of the extraordinary EHT image of shadow attributed to the M87* supermassive black hole (SMBH), we have a novel window to assess the validity of fundamental physics in the strong-field regime. Motivated by this, we consider Johannsen & Psaltis metric parameterized by mass, spin, and an additional dimensionless hair parameter ϵ. This parametric framework in the high rotation regimes provides a well-behaved bed to the strong-gravity test of the no-hair theorem (NHT) using… Expand

The apparent angular size of the shadow of a black hole in an expanding Universe is redshift-dependent. Since cosmological redshifts change with time known as the redshift drift allExpand

Metric for rapidly spinning black holes suitable for strong-field tests of the no-hair theorem
According to the no-hair theorem, astrophysical black holes are uniquely characterized by their masses and spins and are described by the Kerr metric. Several parametric deviations from the KerrExpand

According to the no-hair theorem, all astrophysical black holes are fully described by their masses and spins. This theorem can be tested observationally by measuring (at least) three differentExpand
Gravitational Test beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole.
TLDR
It is shown analytically that spacetimes that deviate from the Kerr metric but satisfy weak-field tests can lead to large deviations in the predicted black-hole shadows that are inconsistent with even the current EHT measurements. Expand
Testing the No-Hair Theorem with GW150914.
TLDR
Analysis of gravitational-wave data from the first LIGO detection of a binary black-hole merger finds evidence of the fundamental quasinormal mode and at least one overtone associated with the dominant angular mode, and supports the hypothesis that the GW150914 merger produced a Kerr black hole, as predicted by general relativity.

Parameter estimation of hairy Kerr black holes from its shadow and constraints from M87*
The recently obtained hairy Kerr black holes, due to additional sources or surrounding fluid, like dark matter, with conserved energy-momentum tensor, have a deviation U and primary hair ;0, apartExpand

Can supermassive black hole shadows test the Kerr metric?
The unprecedented image of the M87* supermassive black hole has sparked some controversy over its usefulness as a test of the general relativistic Kerr metric. The criticism is mainly related to theExpand
