Biography/History:

Andrei Mesinger obtained his PhD from Columbia University in 2006. After a postdoc at Yale University, and a Hubble fellowship at Princeton University, he moved to Scuola Normale Superiore in Pisa in 2011 as junior faculty. He has authored over 100 publications on early structure formation and the epoch of reionization, as well as creating the widely-used public simulation code, 21cmFAST. In 2015, his research was recognized with a prestigious 1.5 million euro Starting Grant award from the European Research Council.

Summary:

The redshifted 21-cm signal is set to transform astrophysical cosmology, bringing a historically data-starved field into the era of Big Data. Corresponding to the spin-flip transition of neutral hydrogen, the 21-cm line is sensitive to the temperature and ionization state of the cosmic gas, as well as to cosmological parameters. Crucially, with the development of new interferometers it will allow us to map out the first billion years of our universe, enabling us to learn about the properties of the unseen first generations of galaxies. Rapid progress is being made on both the observational and theoretical fronts, and important decisions on techniques and future direction are being made. The Cosmic 21-cm Revolution gathers contributions from current leaders in this fast-moving field, providing both an overview for graduate students and a reference point for current researchers.
