The Final Frontier: Galaxies at the Epoch of Reionization

Maruša Bradač

UC Davis, USA

When did galaxies start forming stars? What is the role of distant galax-
ies in galaxy formation models and the epoch of reionization? What are
the conditions in typical low-mass, star-forming galaxies at z ∼ 6 and
above? Recent observations with HST and Spitzer indicate several crit-
ical puzzles in studies that address these questions. Chief among those
– galaxies – might have started forming stars earlier than previously
thought (< 400 Myr after the Big Bang). Their star formation history
differs from what is predicted from simulations. I will present the latest
results from our deep HST and Spitzer surveys showing successful mea-
surements of the properties of stellar populations and identifying new
puzzles facing future surveys at z ∼ 7 and beyond.
