LIGO Inspiral Analysis Workflow

The Laser Interferometer Gravitational Wave Observatory (LIGO) is attempting to detect gravitational waves produced by various events in the universe as per Einstein's theory of general relativity. The LIGO Inspiral Analysis Workflow is used to analyze the data obtained from the coalescing of compact binary systems such as binary neutron stars and black holes. The time-frequency data from any event for each of the three LIGO detectors is split into smaller blocks for analysis. For each block, the workflow generates a subset of waveforms belonging to the parameter space and computes the matched filter output. If a true inspiral has been detected, a trigger is generated that can then be checked with triggers for the other detectors. Several additional consistency tests may also be performed.
