Evolution to a smooth universe in an ekpyrotic contracting phase with w > 1
David Garfinkle, Woei Chet Lim, Frans Pretorius +1
A period of slow contraction with equation of state w > 1, known as an ekpyrotic phase, has been shown to flatten and smooth the universe if it begins the phase with small perturba…
The high-energy collision of two black holes
U. Sperhake, V. Cardoso, F. Pretorius +2
We study the head-on collision of two highly boosted equal mass, nonrotating black holes. We determine the waveforms, radiated energies, and mode excitation in the center of mass f…
Binary Black Hole Coalescence
Frans Pretorius
The two-body problem in general relativity is reviewed, focusing on the final stages of the coalescence of the black holes as uncovered by recent successes in numerical solution of…
A data-analysis driven comparison of analytic and numerical coalescing binary waveforms: nonspinning case
Yi Pan, Alessandra Buonanno, John G. Baker +5
We compare waveforms obtained by numerically evolving nonspinning binary black holes to post-Newtonian (PN) template families currently used in the search for gravitational waves b…
Black Hole Mergers and Unstable Circular Orbits
Frans Pretorius, Deepak Khurana
We describe recent numerical simulations of the merger of a class of equal mass, non-spinning, eccentric binary black hole systems in general relativity. We show that with appropri…
Comparisons of binary black hole merger waveforms
John G. Baker, Manuela Campanelli, Frans Pretorius +1
This a particularly exciting time for gravitational wave physics. Ground-based gravitational wave detectors are now operating at a sensitivity such that gravitational radiation may…
