ABSTRACT:
The recent observations of gravitational waves have been enabled by a new generation of LIGO detectors, Advanced LIGO, the most sensitive laser interferometers ever built. In my talk I will review the main scienctific results from the first two Observing Runs, O1 and O2, and discuss the status of the Advanced LIGO detectors and plans for O3. I will also describe prospects for further extending the astrophysical reach of ground-based observations with future generations of detectors.
