Twisting algebraically special solutions in five dimensions
Gabriel Bernardi de Freitas, Mahdi Godazgar, Harvey S. Reall
We determine the general form of the solutions of the five-dimensional vacuum Einstein equations with cosmological constant for which (i) the Weyl tensor is everywhere type II or m…
Consistent 4-form fluxes for maximal supergravity
Hadi Godazgar, Mahdi Godazgar, Olaf Krueger +1
We derive new ansaetze for the 4-form field strength of D=11 supergravity corresponding to uplifts of four-dimensional maximal gauged supergravity. In particular, the ansaetze dire…
Linear mode stability of Kerr-Newman and its quasinormal modes
Oscar J. C. Dias, Mahdi Godazgar, Jorge E. Santos
We provide strong evidence that, up to of extremality, Kerr-Newman black holes (KN BHs) are linear mode stable within Einstein-Maxwell theory. We derive and solve, numer…
Uniqueness of the Kerr-de Sitter spacetime as an algebraically special solution in five dimensions
Gabriel Bernardi de Freitas, Mahdi Godazgar, Harvey S. Reall
We determine the most general solution of the five-dimensional vacuum Einstein equation, allowing for a cosmological constant, with (i) a Weyl tensor that is type II or more specia…
