Welcome to the Georgia Tech catalog of binary black hole simulations. The publication describing this catalog can be found on Classical & Quantum Gravity “Georgia tech catalog of gravitational waveforms”
The catalog contains 452 unique simulations. These simulations can be used to analyze the dynamics and data-analysis for gravitational-waves from a binary black hole coalescence. In this site you will find a information about:
- Table summarizing the binary black hole parameter space of the catalog
- Gravitational-waveform for a given simulation and relevant scripts
- Raw simulation data
- Technical details about the simulations

GRAVITATIONAL WAVEFORMS
To download ready to use gravitational-waveforms for entire catalog click here
These waveform are in LSC-hdf5 format and can be scaled to a given total-mass and distance. The scripts to read these waveforms can be found here.

TECHNICAL INFORMATION
- In each simulation, binary black holes are scaled to total mass set by the apparent horizon mass at the start of the simulation (ideally, Mtot = 1).
- All gravitational-waveforms (LSC-hdf5 format) contain radiated modes l=2:6, m=-l:l. The waveforms are computed at finite extraction radius and finite resolution. Initial junk radiation is removed from these waveforms.
- Waveforms from multiple extraction radius and individual modes are available in raw simulation data.
- Spins, masses and momenta are defined at the start of the simulation.
