A prominent research theme at ASTRON involves the study of Cosmic Dawn (CD) and Epoch of Reionization (EoR) with LOFAR. These eras span the first billion years of the Universe’s history when the first stars and galaxies appeared and died, forming the first elements that make up everything that we see around us today. This period in the history of the Universe remains the least explored. Advancing our understanding of this early universe has been a primary motivation for the construction of the Square Kilometre Array.

Most of the current group members are based at ASTRON and the Kapteyn Astronomical Institute of the University of Groningen, but the team involves members from e.g. the UK, Germany and Sweden.
