Cosmic Dawn
The Experiment to Detect the Global Eor Signal is a “global 21cm signal” experiment. It reported the first evidence of the very first stars in the Universe in 2018.
I develop EDGES’ analysis pipeline for everything from data formats to calibration to data reduction and interpretation. I am particularly interested in validating our pipeline with Bayesian statistical models.
The Hydrogen Epoch of Reionization Array is one of the largest radio interferometers in the world, and is looking to map the effects of the first stars, galaxies and black holes over the first billion years of the Universe.
I co-lead the Validation Team, developing increasingly realistic simulations of our observations at scale. I also lead the development of an interface to compute theoretical likelihoods on HERA data.
The SKA will be the largest radio telescope ever built, with a collecting area of over a square kilometre. It will be able to detect the faintest signals from the early Universe, and will be able to image the sky with unprecedented resolution.
I am a member of the EoR and Cosmic Dawn Science Working Group, contributing to the development of our tools and techniques, to be ready for the insane amount of data we’re going to get when SKA comes online.
