DESCRIPTION:Identifying low-redshift galaxies that emit Lyman Continuum ra
 diation is one of the primary\, indirect methods of studying galaxy format
 ion in the epoch of reionization. However\, not only has it proved challen
 ging to identify such systems\, but it also remains uncertain whether the 
 low-redshift LyC leakers are true "analogues" of the sources that reionize
 d the Universe. I will talk about how we use high-resolution cosmological 
 radiation hydrodynamics simulations to examine whether simulated galaxies 
 in the epoch of reionization share similar emission-line properties to obs
 erved LyC leakers at z~3 and z∼0. Furthermore\, I will discuss how we us
 e our simulated galaxies to develop multiple new diagnostics\nto identify 
 LyC leakers using IR and nebular emission lines and how they can be applie
 d to galaxies at redshifts as high at z=9.1.
