A parametrization to test black hole candidates with the spectrum of thin disks
Nan Lin, Naoki Tsukamoto, M. Ghasemi-Nodehi +1
We discuss a parametrization to describe possible deviations from the Kerr metric and test astrophysical black hole candidates with electromagnetic radiation. Our metric is a very…
Testing the no-hair theorem with the continuum-fitting and the iron line methods: a short review
Cosimo Bambi, Jiachen Jiang, James F. Steiner
The continuum-fitting and the iron line methods are leading techniques capable of probing the spacetime geometry around astrophysical black hole candidates and testing the no-hair…
Wormholes and nonsingular space-times in Palatini gravity
Cosimo Bambi, Alejandro Cardenas-Avendano, Gonzalo J. Olmo +1
We reconsider the problem of theories of gravity coupled to Born-Infeld theory of electrodynamics formulated in a Palatini approach, where metric and connection are independ…
Testing black hole candidates with electromagnetic radiation
Cosimo Bambi
Astrophysical black hole candidates are thought to be the Kerr black holes of general relativity, but there is not yet direct observational evidence that the spacetime geometry aro…
Scattering of particles by deformed non-rotating black holes
Guancheng Pei, Cosimo Bambi
We study the excitation of axial quasi-normal modes of deformed non-rotating black holes by test-particles and we compare the associated gravitational wave signal with that expecte…
Modified gravity in three dimensional metric-affine scenarios
Cosimo Bambi, M. Ghasemi-Nodehi, D. Rubiera-Garcia
We consider metric-affine scenarios where a modified gravitational action is sourced by electrovacuum fields in a three dimensional space-time. Such scenarios are supported by the…
