Abstract
Fast Radio Bursts (FRBs) are recently discovered class of bright, millisecond, extra-Galactic radio pulses whose origins remain illusive. I will present the current state of this rapidly evolving field. Focusing on the well characterized FRB 121102, I will argue that any successful FRB model must now explain a diverse phenomenology, and thus faces severe observational constraints. I will then describe the `concordance magnetar model’ as a first quantitative theory attempting to unify this picture, and will discuss the model implications and testable predictions.
