Slowly rotating black hole solutions in Horndeski gravity
Andrea Maselli, Hector O. Silva, Masato Minamitsuji +1
We study black hole solutions at first order in the Hartle-Thorne slow-rotation approximation in Horndeski gravity theories. We derive the equations of motion including also cases…
Tensor-multi-scalar theories: relativistic stars and 3+1 decomposition
Michael Horbatsch, Hector O. Silva, Davide Gerosa +4
Gravitational theories with multiple scalar fields coupled to the metric and each other --- a natural extension of the well studied single-scalar-tensor theories --- are interestin…
Post-Tolman-Oppenheimer-Volkoff formalism for relativistic stars
Kostas Glampedakis, George Pappas, Hector O. Silva +1
Besides their astrophysical interest, compact stars also provide an arena for understanding the properties of theories of gravity that differ from Einstein's general relativity. Nu…
Testing General Relativity with Present and Future Astrophysical Observations
Emanuele Berti, Enrico Barausse, Vitor Cardoso +50
One century after its formulation, Einstein's general relativity has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests pr…
