The goal of LIGO (Laser Interferometer Gravitational-wave Observatory) is to
measure very small changes in the length of its arms caused by gravitational waves
stretching and compressing space-time. The purpose of this project was to perform a
search pipeline test on the LIGO detector using a point source stochastic signal. Here we
report an effort to test the LIGO stochastic data-analysis pipeline using a simulated
hardware injection. A hardware injection is an end-to-end test that begins with the
generation of a signal and ends with the recovery of the signal from the detector’s strain
data. The signal is injected into the interferometers by actuating on a test mass (or mirror)
in order to shake it to simulate a gravitational wave. We successfully recovered the
hardware injection with measured parameters consistent with injected parameters, thus
providing an end-to-end test of the stochastic data-analysis pipeline.
