The Advanced LIGO detectors in the era of multi-messenger astronomy

Advanced LIGO and Advanced Virgo are currently in the middle of their third observing run; the first to feature open public event alerts. The LIGO-Virgo collaboration has issued 28 un-retracted candidate event alerts as of September 11th, 2019, potentially adding dozens more known compact object mergers to the eleven confident LIGO-Virgo detections from the first two Advanced-era observing runs. I’ll present the Advanced LIGO detectors, give an overview of the cosmic collisions observed by LIGO-Virgo to date, and discuss the challenges of extracting astrophysical signals from noisy detector data.
