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.

The NSF National Radio Astronomy Observatory and NSF Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
