The LIGO-Virgo collaboration has thus far issued 33 un-retracted public candidate event alerts during our third observing run, potentially adding dozens more known compact binary object mergers to the eleven confident detections from the first two Advanced-era observing runs. I’ll give an overview of the process of detecting, characterizing, and assessing the significance of gravitational wave signals registered in Advanced LIGO data. I’ll review novel results from LIGO-Virgo to date, and the challenges of extracting interesting new physics from noisy detector data. Finally, I’ll summarize the roadmap to future gravitational wave detectors on Earth and in space.
