Astro Seminar

Bright galaxies in the first billion years

Speaker: Rebecca Bowler (Oxford)
Date: Wednesday 24 November 2021
Time: 14:00
Venue: Zoom

Studying galaxies at ultra-high redshifts (z > 6) provides a unique insight into the early stages of galaxy formation and evolution. I will give an overview of how star-forming ‘Lyman-break’ galaxies are selected in the first few billion years. I will then show how samples of these objects can constrain the astrophysics at play in early galaxy formation through the observed shape and evolution of the luminosity function. Finally I will present some of the first resolved measurements of the young stars and dust within normal galaxies in the Epoch of Reionization. These results give a sneak preview of the exciting discoveries upcoming from JWST on the earliest stages of galaxy formation and evolution.
