Title: Strong-gravity signatures from relics of the early universe

Abstract: 

Some of the most well-motivated extensions of the standard model of particle physics and general relativity introduce extra fundamental fields that play a key role in mechanisms of the early universe. These phenomena, in turn, lead to the formation of structures that can leave imprints and persist to this day. In this talk I will discuss the use of numerical relativity to study the strong-gravity signatures of these relics, to probe the physics of the early universe.
