Stellar prospects for FRB gravitational lensing

Understand

Gravitational lensing of fast radio bursts (FRBs) offers an exciting avenue for several cosmological applications.

• However, it is not yet clear how many such events future surveys will detect nor how to optimally find them.
• We use the known properties of FRBs to forecast detection rates of gravitational lensing on delay timescales from microseconds to years, corresponding to lens masses spanning fifteen orders of magnitude.
• We highlight the role of the FRB redshift distribution on our ability to observe gravitational lensing.
