Status of LIGO detectors and results from recent astrophysical searches

Research output: Contribution to journalConference article


The Laser Interferometer Gravitational-wave Observatory (LIGO) has built three multi-km scale interferometers, designed to search for gravitational waves. The sensitivity of the LIGO interferometers has been rapidly increasing over the recent years, allowing a number of searches for sources of gravitational waves to be conducted. We discuss the current status of the LIGO interferometers and the results from the recent search for stochastic background of gravitational waves. For the frequency independent gravitational wave spectrum, we report a new Bayesian 90% UL on the spectral amplitude of 8.4 × 10−4 in the frequency range 69-156 Hz.
