The First Stars, Galaxies and Black Holes
Abstract
I will review our current understanding of how star and galaxy formation transformed the conditions in the early universe, in terms of initiating the long cosmic reionization and metal enrichment history. It is timely to take stock of our emerging theoretical framework of the first stars, galaxies and black holes, just ahead of the JWST launch. I will discuss the exciting insights on early star formation, and possibly the particle physics nature of dark matter, from the recent EDGES detection of a global 21cm absorption feature at cosmic dawn.
