Spacetime dynamics of spinning particles - exact electromagnetic analogies
L. Filipe O. Costa, José Natário, Miguel Zilhão
We compare the rigorous equations describing the motion of spinning test particles in gravitational and electromagnetic fields, and show that if the Mathisson-Pirani spin condition…
Mathisson's helical motions demystified
L. Filipe O. Costa, José Natário, Miguel Zilhão
The motion of spinning test particles in general relativity is described by Mathisson-Papapetrou-Dixon equations, which are undetermined up to a spin supplementary condition, the l…
Collisions of charged black holes
Miguel Zilhão, Vitor Cardoso, Carlos Herdeiro +2
We perform fully non-linear numerical simulations of charged-black-hole collisions, described by the Einstein-Maxwell equations, and contrast the results against analytic expectati…
Dynamics of black holes in de Sitter spacetimes
Miguel Zilhao, Vitor Cardoso, Leonardo Gualtieri +3
Nonlinear dynamics in cosmological backgrounds has the potential to teach us immensely about our universe, and also to serve as prototype for nonlinear processes in generic curved…
NR/HEP: roadmap for the future
Vitor Cardoso, Leonardo Gualtieri, Carlos Herdeiro +29
Physics in curved spacetime describes a multitude of phenomena, ranging from astrophysics to high energy physics. The last few years have witnessed further progress on several fron…
