An exploration of CUDA and CBEA for a gravitational wave source-modelling application
Gaurav Khanna, Justin McKennon
In this paper, we accelerate a gravitational physics numerical modelling application using hardware accelerators -- Cell processor and Tesla CUDA GPU. We describe these new technol…
Computational Efficiency of Frequency-- and Time--Domain Calculations of Extreme Mass--Ratio Binaries: Equatorial Orbits
Jonathan L. Barton, David J. Lazar, Daniel J. Kennefick +2
Gravitational waveforms and fluxes from extreme mass--ratio inspirals can be computed using time--domain methods with accuracy that is fast approaching that of frequency--domain me…
Towards adiabatic waveforms for inspiral into Kerr black holes: II. Dynamical sources and generic orbits
Pranesh A. Sundararajan, Gaurav Khanna, Scott A. Hughes +1
This is the second in a series of papers whose aim is to generate ``adiabatic'' gravitational waveforms from the inspiral of stellar-mass compact objects into massive black holes.…
Pion emission in 2H, 12C, 27Al, gamma pi+ reactions at threshold
P. Golubev, V. Avdeichikov, K. G. Fissum +12
The first data from MAX-lab in Lund, Sweden on pion production in photonuclear reactions at threshold energies, is presented. The decrease of the total yield of pi+ in gamma + 12C,…
Numerical solutions to lattice-refined models in loop quantum cosmology
Subir Sabharwal, Gaurav Khanna
In this article, we develop an intuitive and efficient, numerical technique to solve the quantum evolution equation of generic lattice-refined models in loop quantum cosmology. As…
Late-time Kerr tails revisited
Lior M. Burko, Gaurav Khanna
The decay rate of late time tails in the Kerr spacetime have been the cause of numerous conflicting results, both analytical and numerical. In particular, there is much disagreemen…
