DESCRIPTION:Speakers: Chan Chun Lung (The Chinese University of Hong Kong)
 \nStrong gravitational lensing of gravitational waves can produce duplicat
 e signals separated in time with different amplitudes. We consider the cas
 e in which strong lensing produces identifiable gravitational wave events 
 and weaker sub-threshold signals hidden in the noise background. We presen
 t a search method for the sub-threshold signals using targeted template ba
 nks targeting specific confirmed gravitational wave events. We apply the m
 ethod to all the gravitational-wave signals from compact binary coalescenc
 es detected by Advanced LIGO and Advanced Virgo during O3a\, the first hal
 f of their third observing run. Finally\, we present the top 8 possible le
 nsed candidates for O3a gravitational wave events that passed our nominal 
 significance threshold of False Alarm Rate 1 in 16 years. Furthermore\, we
  discuss the likelihood that these candidates are strongly lensed.\n\nhttp
