Strongly lensed extreme mass-ratio inspirals

In this work, we investigate detection rates and parameter estimation of strongly lensed extreme massratio inspirals (LEMRIs) in the context of the Laser Interferometer Space Antenna (LISA). Our results indicate that LEMRIs constitute a new gravitational -wave target signal for LISA, with detection rates ranging from zero to -40 events over a four year -observation period, and that it is possible to reveal and characterize LEMRIs at redshift z greater than or similar to 1. We finally show that one LEMRI observation with identified host galaxy may yield percent constraints or better on the Hubble constant.
