“Fast Radio Bursts: A Cosmological Conundrum or Why I Finally Left the Galaxy”
Fast Radio Bursts (FRBs) are a newly recognized and puzzling phenomenon consisting of few-millisecond bursts of radio waves coming from cosmological distances. They are ubiquitous, with all-sky rates of roughly 1000 per day, signaling a not uncommon yet powerful explosion of presently unknown origin. Recently there has been significant observational progress on understanding FRBs and recognizing their potential as novel cosmological probes, in large part thanks to the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB). In this talk I review what is known about FRBs, and describe some of the latest CHIME/FRB results related to FRB origin and distribution in the Universe.
