This is the Assessment Study Report (also known as the Yellow Book) for THESEUS (Transient High-Energy Sky and Early Universe Surveyor) - a candidate mission for the M5 launch opportunity in Cosmic Vision.

THESEUS is designed to fully exploit the unique and breakthrough potentialities of Gamma-Ray Bursts for investigating the Early Universe and advancing multi-messenger astrophysics, while simultaneously vastly increasing the discovery space of high energy transient phenomena over the entirety of cosmic history.
