Fresh Tracks into Galaxy Formation with Webb

Wed, Mar 6, 5:30–6:30pm
Abstract
The first year of observations from the James Webb Space Telescope has revolutionized our understanding of the Universe. Webb is a 6.5-meter space telescope sensitive to infrared light, detecting the light of ancient galaxies greater than 13 billion years.
These first galaxies seem to be forming earlier and more rapidly than previously thought, defying predictions from our best theoretical models. And the evidence continues to mount — we now find an abundance of oversized supermassive black holes, and, when the Universe was merely one billion years old, we find examples of star formation plummeting in ‘too early’, ‘too massive’ galaxies.
Taken together, our entire knowledge of early galaxy formation is in a state of flux. In this talk, Whitaker will introduce you to the capabilities of NASA’s newest flagship mission and highlight a few of the most exciting and revolutionary results to date. Among these is the story of distinguishing the most distant galaxies from those enshrouded in thick veils of dust while teasing out the hidden monsters inside.

Nick and Maggie DeWolf Public Lecture Series
The Nick and Maggie DeWolf Foundation has sponsored our winter public lecture series since their inception in 1985. The Nick and Maggie DeWolf Foundation is a nonprofit organization based in Aspen, Colorado. Its core tenet is to provide support to groups and organizations interested in improving the quality of life and education in the world. During the winter, Aspen Center for Physics hosts week-long conferences, and during each conference one of the conference participants is asked to give a public physics talk. You can watch past talks on our YouTube channel here.
