Characteristic features of gravitational wave lensing as probe of lens mass model

Understand

To recognize gravitational wave lensing events and being able to differentiate between similar lens models will be of crucial importance once one will be observing several lensing events of gravitational waves per year.

• In this work, we study the lensing of gravitational waves in the context of LISA sources and wave-optics regime.
• While different papers before ours studied microlensing effects enhanced by simultaneous strong lensing, we focus on frequency (time) dependent phase effects produced by one lens that will be visible with only one lensed image.
• We will show how, in the interference regime (i.e.
