Light Deflection due to Spinoptic Effects in Parametrized and Spherically Symmetric Hairy Black Holes
Kelvin S. Alves, Rogerio T. Cavalcanti, Santiago E. Perez Bergliaffa
In the standard geometric optics approximation, null rays propagating in a spherically symmetric black hole background follow planar geodesics. This picture changes, however, when…

Hair imprints of the gravitational decoupling and hairy black hole spectroscopy
V. F. Guimarães, R. T. Cavalcanti, R. da Rocha
Hairy black holes by gravitational decoupling (GD) are probed to derive the gravitational waveform produced by perturbation theory applied to these compact objects. Using the Regge…
