Pattern of lensed chirp gravitational wave signal and its implication on the mass and position of lens

Understand

We prose a new measurement strategy of the estimation of the lens mass, as well as the actual amplification, of the lens through the modulation patten of lensed gravitational wave signals alone.

• This can be done by measuring the frequency and amplitude ratio of peaks and valleys of the modulation pattern of CBC signals, known as "beat", which is a time domain phenomenon of strong lens effect.
