Researcher - Dr Jack Line | Curtin University, Perth, Australia

Introduction

I'm currently a member of the Epoch of Reionisation science group at Curtin Institude of Radio Astronomy. As such I'm interersted in studying and observing the very first stars and galaxies that existing in the Universe, which we think switched on somewhere around 13 billion years ago. Most of my work is done using the Murchison Widefield Array which is a low frequency instrument that does science at the same frequencies as JJJ bangs out tunes.
