Palatini Approach Beyond Einstein's Gravity
Gonzalo J. Olmo
I review recent results obtained for extensions of general relativity formulated within the Palatini formalism, an approach in which metric and connection are treated as independen…
Relativistic positioning: four-dimensional numerical approach in Minkowski space-time
Neus Puchades, Diego Sáez
We simulate the satellite constellations of two Global Navigation Satellite Systems: Galileo (EU) and GPS (USA). Satellite motions are described in the Schwarzschild space-time pro…
Nonsingular black holes in quadratic Palatini gravity
Gonzalo J. Olmo, D. Rubiera-Garcia
We find that if general relativity is modified at the Planck scale by a Ricci-squared term, electrically charged black holes may be nonsingular. These objects concentrate their mas…
Palatini approach to bouncing cosmologies and DSR-like effects
Gonzalo J. Olmo
It is shown that a quadratic gravitational Lagrangian in the Palatini formulation is able to capture different aspects of quantum gravity phenomenology in a single framework. In pa…
Maximal slicings in spherical symmetry: local existence and construction
Isabel Cordero-Carrión, José María Ibáñez, Juan Antonio Morales-Lladosa
We show that any spherically symmetric spacetime locally admits a maximal spacelike slicing and we give a procedure allowing its construction. The construction procedure that we ha…
On the Bel radiative gravitational fields
Joan Josep Ferrando, Juan Antonio Sáez
We analyze the concept of intrinsic radiative gravitational fields defined by Bel and we show that the three radiative types, N, III and II, correspond with the three following dif…
