Radio Cosmology and the Cosmic Dawn — •Jonathan Pritchard — Max Planck Institute for Radio Astronomy

In this talk, I will review the status of experiments attempting to detect the 21cm signal from reionization and the time of the first galaxies, In particular, I will discuss 21cm global experiments, especially REACH - a global 21 cm experiment deployed in the the Karou in South Africa. I will also discuss some of the preparation work for epoch of reionization studies with the Square Kilometre Array and describe applications of machine learning algorithms for inferring science from 21cm observations.
