DESCRIPTION:Speakers: William DeRocco (University of Maryland\, College Pa
 rk)\n\nMacroscopic objects\, e.g. primordial black holes (PBHs)\, may cons
 titute a sub-fraction of the dark sector in the Earth-mass range. The stro
 ngest observational probe of such a population is through gravitational mi
 crolensing\, an effect in which the bending of light by a massive object r
 esults in the apparent transient magnification of a distant source. While 
 ground-based observatories have produced tantalizing hints of a PBH popula
 tion in this mass range\, our understanding of this potential signal will 
 be transformed with the launch of the Roman Space Telescope in 2026\, whos
 e Galactic Bulge Time Domain Survey will usher in a new era of discovery i
 n this field. In this talk\, I will discuss how by leveraging the high-sta
 tistics observations that Roman will make\, we will be able to discern mul
 tiple subpopulations of non-luminous lenses\, providing a new window into 
 both planetary formation and fundamental physics.\n\nhttps://events.perime
