Title:  Finding the most distant galaxies in the universe with JWST

Abstract: James Webb Space Telescope (JWST) has opened a new window into the early universe, enabling sensitive, high-resolution images of the near-infrared sky and spectroscopy of faint, distant sources. The JWST Advanced Deep Extragalactic Survey (JADES) is an international collaboration pooling more than 750 hours of JWST time to conduct an ambitious study of galaxy evolution, concentrating on two areas of the sky called GOODS-South and GOODS-N originally made famous by Hubble Space Telescope. I will discuss exciting results from JADES observations about discoveries in the distant (z>10!) universe, only a few hundred million years after the Big Bang, that provide new insight into the process of early galaxy formation and cosmic reionization. We discuss how our new constraints on star formation and galaxy growth at the very earliest times are rewriting the story of how the first galaxies form and evolve.

Visitor's room: 127

Visit Schedules:

As you know, Brant Robertson of the University of California, Santa Cruz, will be visiting us for two weeks starting next Monday (April 29).  While he is here, he will give the colloquium on Tuesday (the final one of the semester!) and four additional lectures.  The schedule, title, and abstracts of his five talks is attached below (no changes from the version Mindy sent around last week).  

  Tuesday’s talk will be followed by Bahcall Lunch (again, the final one of the semester).  And we will take Brant out for dinner on Tuesday evening; all the spots for dinner are already filled.   

  Given that Brant will be here for two weeks (sitting in Peyton 127: Eliot’s office), there will be plenty of opportunity to talk with him.  You can sign up to do so here.
