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…
Graviton time delay and a speed limit for small black holes in Einstein-Gauss-Bonnet theory
Giuseppe Papallo, Harvey S. Reall
Camanho, Edelstein, Maldacena and Zhiboedov have shown that gravitons can experience a negative Shapiro time delay, i.e. a time advance, in Einstein-Gauss-Bonnet theory. They studi…
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…
