Emma Chapman

Emma Chapman Emma Olivia Chapman (née Woodfield, born 1988) is a British astrophysicist, known for her research on the epoch of reionisation and her public commentary on astronomy, astrophysics, and gender equality issues in the sciences. She is the author of the 2020 popular science book First Light: Switching on Stars at the Dawn of Time and the 2026 popular science book Radio Universe: How to Explore Space without Leaving Earth (UK title) / The Echoing Universe: How Radio Astronomy Helps Us See the Invisible Cosmos (US title). Quotes The EoR foregrounds can be up to three magnitudes greater than the cosmological signal we wish to detect. Multiple methods have been developed in order to extract the cosmological signal, falling roughly into three categories: foreground removal, foreground suppression and foreground avoidance. 2017 Foreground Mitigation in the Epoch of Reionization Proceedings of the International Astronomical Union 12 S333 261–268 https://doi.org/10.1017/S1743921317010419 10.1017/S1743921317010419 The Era of the First Stars is one of the last unknown frontiers for exploration: a poorly understood billion years missing from our cosmological timeline. We have now developed several methods for finally filling in the lost billion years of the history of our Universe: stellar archaeology, detecting primordial hydrogen using Hydrogen line 21 cm cosmological emission, and observing the earliest galaxies, most recently using the James Webb Space Telescope. This review will summarise why the first stars and galaxies are unique and worthy of observation, and the methods employed by the groundbreaking telescopes aiming to detect them.
