Title: Searching for strongly lensed sub threshold gravitational waves

Abstract:
Based on the rate of detections made in this advanced era of gravitational-wave detectors, we expect LIGO, Virgo, and KAGRA to detect hundreds of binary black hole mergers in the next few years. Of these detections, it is expected that a small fraction of them can undergo strong gravitational lensing, as a result of intervening galaxies between the source and the detectors. Strong gravitational lensing can produce duplicate signals that are separated in time with different amplitudes. In this talk, I will describe current search methods to detect such sub threshold gravitational wave events.
