SUMMARY:Simulating Radio Strong Gravitational Lenses for the Dark Matt
 er Substructure Inference Problem\, Preliminary Exam\, Joyce Lin
DESCRIPTION:In the next 10 years\, there will be more sky data than ev
 er with the Vera C. Rubin Observatory\, Euclid Space Telescope\, Roman
  Space Telescope\, and SKA Observatory. With these telescopes\, hundre
 ds of thousands of strong gravitational lenses are expected to be iden
 tified changing the landscape of dark matter research. Follow-up obser
 vations using high resolution VLBI will unveil the delicate features i
 n these radio strong lenses allowing for the opportunity to probe low 
 mass perturbers such as line-of-sight dark matter halos. Only two syst
 ems with VLBI data have been studied to date resulting in the first mi
 llion solar mass object detected at cosmological distances. Using grav
 itational lensing simulations\, we present a forecast on how many of t
 hese radio strong gravitational lenses exist and are useful for dark m
 atter substructure constraints.
