High Energy Collisions of Black Holes Numerically Revisited
James Healy, Ian Ruchlin, Carlos O. Lousto +1
We use fully nonlinear numerical relativity techniques to study high energy head-on collision of nonspinning, equal-mass black holes to estimate the maximum gravitational radiation…
Spin flips in generic black hole binaries
Carlos O. Lousto, James Healy, Hiroyuki Nakano
We study the spin dynamics of individual black holes in a binary system. In particular we focus on the polar precession of spins and the possibility of a complete flip of spins wit…
Perturbative extraction of gravitational waveforms generated with Numerical Relativity
H. Nakano, J. Healy, C. O. Lousto +1
We derive an analytical expression for extracting the gravitational waveforms at null infinity using the Weyl scalar measured at a finite radius. Our expression is based on a…
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…
