Description
The use of sophisticated seismic isolation has enabled Advanced LIGO to be sensitive to lower frequency gravitational-waves compared to initial LIGO, which has been crucial for the recent detections of binary black-hole merger signals. The seminar will describe one of the key upgrades in Advanced LIGO, the active seismic isolation subsystem, and how their performance is being improved using high-precision ground-rotation sensors.
