Gravitational wave astronomy is beginning for real at this moment.
Following the first detection of gravitational waves from the merger of a binary black hole in 2015, the LIGO and VIRGO collaboration already collected six significant gravitational wave events in total so far, one of which was the merger of a neutron star binary. I had been working at one of the sites, the LIGO Hanford observatory, for five years since 2012 and putting a large effort of making the detectors running with low noise in a robust manner. As one might imagine, the road to these glorious achievements was not easy---perhaps it was rather long and winding. In this seminar, I would like to share the excitement of these detections that I luckily experienced at the site, explain some of the experimental challenges that we encountered and review the current status of the gravitational wave detectors.
