Robustness of slow contraction to cosmic initial conditions
Anna Ijjas, William G. Cook, Frans Pretorius +2
We present numerical relativity simulations of cosmological scenarios in which the universe is smoothed and flattened by undergoing a phase of slow contraction and test their sensi…
Supersmoothing through Slow Contraction
William G. Cook, Iryna A. Glushchenko, Anna Ijjas +2
Performing a fully non-perturbative analysis using the tools of numerical general relativity, we demonstrate that a period of slow contraction is a `supersmoothing' cosmological ph…
The high-energy collision of black holes in higher dimensions
Ulrich Sperhake, William Cook, Diandian Wang
We compute the gravitational wave energy radiated in head-on collisions of equal-mass, nonspinning black holes in up to dimensional asymptotically flat spacetim…
Black-hole head-on collisions in higher dimensions
William G. Cook, Ulrich Sperhake, Emanuele Berti +1
The collision of black holes and the emission of gravitational radiation in higher-dimensional spacetimes are of interest in various research areas, including the gauge-gravity dua…
