A Precision Wideband Radio Spectrometer to Explore Cosmic Dawn

Project: Research project

Project Details

Description

The history of star formation in the Universe is one of the most fundamental questions of astrophysics. Developing a complete picture of this history is central to understanding our Cosmic Origins. Yet we have little knowledge of the first billion years when the first galaxies and black holes formed and the Universe underwent a global phase transition from neutral to ionized during the Epoch of Reionization (EoR). During this era of Cosmic Dawn are some of the most critical events in the history of the Universe. It is the fundamental period when primordial density fluctuations following inflation evolved through baryon in-fall, adiabatic cooling, and gravitational collapse to create compact structures for the first time. But probing this era is beyond the capabilities of today's instruments. New approaches are needed to enable break-through observations.
