After years of research and planning, the first-generation detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) have been assembled and have begun operation in Livingston, Louisiana, and in Hanford, Washington. LIGO's operating principle is to use precision laser interferometry to measure the relative motion of seismically-isolated test mass mirrors due to the extremely small forces from gravitational waves (GW's) emitted by distant astrophysical events. The test masses are placed at the ends and vertex of a 4 km, L-shaped vacuum system, in order to be sensitive to the extremely small time-varying quadrupole strain in the gravitational field metric that is expected from incident GW's in the 50 Hz - 5 kHz band. This talk will summarize the collaboration's progress to date in understanding and decreasing the instrumental noise sources, as well as in developing and using LIGO's analysis pipeline on data from recent runs, in the context of astrophysical source possibilities.
