RESEARCH GROUP SCHMITZ: Particle Cosmology Münster

© NAOJ

Overview

Welcome! This is the page of the Particle Cosmology Münster research group at the Institute for Theoretical Physics. The research group was established in May 2022 and is headed by Kai Schmitz, a newly appointed junior professor in the Physics Department at the University of Münster. The group deals with research topics at the interface of particle physics and cosmology, notably gravitational waves from the early Universe, and is involved in the activities of the NANOGrav Pulsar Timing Array Collaboration. On this page, you will find more information on the following topics ...
