SPEAKER: Ryan Endsley of Steward Observatory
TITLE: Detecting the Earliest Galaxies in the Universe
ABSTRACT:  Since the launch of the Hubble Space Telescope our understanding of the early universe has been revolutionized by deep legacy surveys such as the Hubble Ultra Deep Field. I will discuss the current state of knowledge gained from these surveys including galaxy formation/evolution and reionization. Then I will discuss how the James Webb Space Telescope (JWST), set to launch in October 2018, will propel our understanding of the very early universe to unprecedented heights. With JWST, we will be able to look back to when the universe was only ~2% of it's current age which is when the very first galaxies in the universe are thought to form and begin reionizing the universe!

BIOGRAPHY:  Ryan Endsley is currently a graduate student at the U of A. He graduated from Washington University in St. Louis with a BA in physics and mathematics. He then spent a year working at the Max Planck Institute for Astrophysics near Munich, Germany. Now a PhD student in the Department of Astronomy, Ryan researches properties of stars and gas in galaxies when the universe was only 5-10% of its current age. By using various UA directed telescopes and resources, Ryan seeks to gain a deeper insight into how galaxies formed and evolved in the early universe and how they built the universe we live in today.
