PyCBC
Software used in gravitational-wave astronomy
From Wikipedia, the free encyclopedia
PyCBC is a free and open-source software package primarily written in the Python programming language which is designed for use in gravitational-wave astronomy and gravitational-wave data analysis.[1] PyCBC contains modules for signal processing, fast Fourier transforms, matched filtering, gravitational waveform generation, among other tasks common in gravitational-wave data analysis.[1]

The software is developed by the gravitational-wave community alongside LIGO and Virgo scientists to analyze gravitational-wave data, search for gravitational-waves, and to measure the properties of astrophysical sources. It has been used to analyze gravitational-wave data from LIGO and VIRGO to detect gravitational-waves from the mergers of neutron stars[2] and black holes[3][4][5][6] and determine their statistical significance.[7] PyCBC-based analyses can integrate with the Open Science Grid for large scale computing resources.[8] Software based on PyCBC has been used to rapidly analyze gravitational-wave data for astronomical follow-up.[9][10][11]
