Observing the universe in the Ultraviolet

 

 

 

Prof. Hamden is a telescope builder, with a focus on UV astronomy and developing new detector technology. She will describe why the UV is so interesting scientifically and why is it criminally understudied. She will also discuss her own work on several different UV missions in development, including FIREBall-2 and Aspera.

 

 

Dr. Erika Hamden is a professor of astrophysics at the University of Arizona. She specializes in building telescopes that go into space and the stratosphere, and developing technology to make telescopes better. Erika is a leader in the field of space astrophysics, and has developed programs to teach early career scientists how to develop their own space missions. She is the deputy principal investigator of Aspera, a NASA orbiting telescope in development. She is a former chef, a TED Fellow, a AAAS If/then Ambassador, an aspiring astronaut, and is working on her pilots license.

Puzzles in Galaxy Evolution

 

 

 

I will describe a pair of sharp puzzles suggesting a possible mismatch between our theory of galaxy evolution and recent observations from the James Webb Space Telescope (JWST). First, current models predict that most distant galaxies found by JWST should be seen at a time when they are transitioning from the initial assembly of their ingredients to the later processes by which they form stars, and other structures we recognize as a galaxy.  Instead, fully-formed, massive galaxies appear to exist impossibly early, before their ingredients should even have been able to assemble.  Second, a possible explanation for this would be that most galaxies grow very differently from the processes we have observed in star-forming regions of our own Milky Way.  I will discuss whether such a difference might be able to reconcile both problems, or whether something is still “broken”.

Charles Steinhardt is an associate professor at the Cosmic Dawn Center and University of Copenhagen, having previously spent time at Caltech, Kavli IPMU, Harvard, and Princeton.  His research is inspired by astrophysical phenomena whose explanation has been cast into doubt, either by new theoretical ideas or new observations.  Recently, this includes several different areas of astronomy and astrophysics, including galaxy evolution, black hole accretion, and gamma-ray bursts.  Recent work also includes developing machine learning and statistical methods for making full use of the large datasets modern astronomy produces.  He also runs a summer undergraduate research program that brings American students to Copenhagen each summer.
