Strongly lensed gravitational waves from intrinsically faint double compact binaries - prediction for the Einstein Telescope

Understand

With a fantastic sensitivity improving significantly over the advanced GW detectors, Einstein Telescope (ET) will be able to observe hundreds of thousand inspiralling double compact objects per year.

• By virtue of gravitational lensing effect, intrinsically unobservable faint sources can be observed by ET due to the magnification by intervening galaxies.
• We explore the possibility of observing such faint sources amplified by strong gravitational lensing.
• Following our previous work, we use the merger rates of DCO (NS-NS,BH-NS,BH-BH systems) as calculated by Dominik et al.(2013).
