What if ... General Relativity is not the theory?
Orfeu Bertolami
The nature of gravity is fundamental to understand the scaffolding of the Universe and its evolution. Einstein's general theory of relativity has been scrutinized for over ninety f…
Mimicking dark matter in galaxy clusters through a non-minimal gravitational coupling with matter
Orfeu Bertolami, Pedro Frazão, Jorge Páramos
In this work, one shows that a specific non-minimal coupling between the scalar curvature and matter can mimic the dark matter component of galaxy clusters. For this purpose, one a…
Higher-dimensional puncture initial data
Miguel Zilhão, Marcus Ansorg, Vitor Cardoso +4
We calculate puncture initial data, corresponding to single and binary black holes with linear momenta, which solve the constraint equations of D dimensional vacuum gravity. The da…
On the dynamics of perfect fluids in non-minimally coupled gravity
Orfeu Bertolami, António Martins
In this work we explore the consequences that a non-minimal coupling between geometry and matter can have on the dynamics of perfect fluids. It is argued that the presence of a sta…
Probing the Flyby Anomaly with the Galileo Constellation
O. Bertolami, F. Francisco, P. J. S. Gil +1
In the last few years, the so-called flyby anomaly has been widely discussed, but remains still an illusive topic. This is due to the harsh conditions experienced during an Earth f…
Mathisson's helical motions for a spinning particle --- are they unphysical?
L. Filipe O. Costa, Carlos A. R. Herdeiro, José Natário +1
It has been asserted in the literature that Mathisson's helical motions are unphysical, with the argument that their radius can be arbitrarily large. We revisit Mathisson's helical…
OSS (Outer Solar System): A fundamental and planetary physics mission to Neptune, Triton and the Kuiper Belt
Bruno Christophe, Linda J. Spilker, John D. Anderson +46
The present OSS mission continues a long and bright tradition by associating the communities of fundamental physics and planetary sciences in a single mission with ambitious goals…
Mass inflation in a D dimensional Reissner-Nordstrom black hole: a hierarchy of particle accelerators ?
P. P. Avelino, A. J. S. Hamilton, C. A. R. Herdeiro +1
We study the geometry inside the event horizon of perturbed D dimensional Reissner-Nordstrom-(A)dS type black holes showing that, similarly to the four dimensional case, mass infla…
