Simulating eXtreme Spacetimes collaboration

Welcome to the github repos of the Simulating eXtreme Spacetimes (SXS) collaboration! We develop and run supercomputer code for numerically simulating black holes, neutron stars, and beyond.

Quick links:

Quick code links:

  • spectre
  • SpEC (members only)
  • Python codes for analyzing simulation outputs
    • sxs: read catalog metadata, waveforms, etc.
    • gwsurrogate: evaluate rapid NR-based waveform surrogate
