White holes in Einstein-aether theory
Ratindranath Akhoury, David Garfinkle, Nishant Gupta
We perform numerical simulations of gravitational collapse in Einstein-aether theory. We find that under certain conditions, the collapse results in the temporary formation of a wh…
Numerical Relativity Beyond Astrophysics
David Garfinkle
Though the main applications of computer simulations in relativity are to astrophysical systems such as black holes and neutron stars, nonetheless there are important applications…
A simple estimate of gravitational wave memory in binary black hole systems
David Garfinkle
A simple estimate is given of gravitational wave memory for the inspiral and merger of a binary black hole system. Here the memory is proportional to the total energy radiated and…
Do spikes persist in a quantum treatment of spacetime singularities?
Ewa Czuchry, David Garfinkle, John R. Klauder +1
The classical approach to spacetime singularities leads to a simplified dynamics in which spatial derivatives become unimportant compared to time derivatives, and thus each spatial…
