**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

**CATALOG TABLE**

The table summarizing the catalog of our simulations (initial parameters of binary black holes and remnant black hole) can be **downloaded here**

**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**.

**RAW SIMULATION DATA**

The raw simulation data contain:

- gravitational-waveforms (inspiral, merger, ringdown with radiated modes)
- black-hole trajectories and spin evolution
- radiated energy, linear and angular momentum
- horizon shapes of initial and final black hole
- mass, spin and recoil velocity of final black hole

An example of a non-spinning, equal-mass binary black hole simulation data (GT0448) can be **downloaded here** (3.1 GB)

**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.
