Cosmology with radio waves: from dark matter to the dark ages (Rennan Barkana)

QG visitor seminar for general OIST audience.
Speaker: Rennan Barkana (Tel Aviv University).
Title: "Cosmology with radio waves: from dark matter to the dark ages"

The coming confrontation of the theory and observations of cosmological radio waves will reveal to us new chapters in the history of the Universe. One of them is the cosmic dawn (the era of the formation of the first stars and galaxies), a cosmic epoch with unique conditions, and thus potential for new discoveries. Another is the dark ages, which could become a powerful new probe of fundamental cosmology. Upcoming experiments, from Earth to the moon, can shine new light on cosmic history and probe the properties of dark matter.
