Title: Gravitational Wave Detectors during the 4th Observing Run of the Advanced Detector Era

Abstract: The era of gravitational wave astronomy has accelerated rapidly, from the first direct detection of gravitational waves in 2015 to our current observing run with candidate events detected several times per week.  The Laser Interferometer Gravitational wave Observatory (LIGO) is jointly operated by Caltech and MIT for the National Science Foundation, and is currently in an observing phase that began in May 2023, and will continue through 2024. I will discuss innovations that have enabled the unprecedented sensitivity of the Advanced LIGO detectors, plans for future upgrades, as well as the exciting plethora of gravitational wave candidates we have seen so far in our 4th observing run.

Bio: Dr. Jenne Driggers is the Detection Lead Scientist at the LIGO Hanford Observatory.  She completed her PhD at the LIGO Caltech 40m interferometer prototype in 2015, and was a postdoc at the LIGO Hanford Observatory before joining the observatory staff.
