62. Black-Hole Mimickers and Dark-Matter Candidates: Modeling Boson Stars and their Gravitational-Wave Signatures

Ulrich Sperhake (University of Cambridge)

Boson stars are compact objects composed of fundamental fields
arising in theories beyond the standard model (SM) of particle physics.
From dark-matter halos to ultracompact objects with light rings,
they have acquired an important role in gravitational-wave driven
searches for physics beyond the "GR+SM" paradigm. In this talk
we present an overview of the modeling of boson-star...
