Physics and Astronomy Colloquium - Professor Dragan Huterer, U of Michigan

Topic: Cosmology | Title: Cosmological results from the Dark Energy Spectroscopic Instrument

4/3/2026
2:15 pm – 3:15 pm
Wilder Hall and Zoom
Intended Audience(s): Public
Categories: Lectures & Seminars, School of Arts and Sciences

Abstract: A quarter-century after the discovery of the accelerated expansion of the universe, the constraints on dark energy that powers this acceleration have become very good, but the physical nature of dark energy remains elusive. I will present and discuss cosmological results from the measurement of baryon acoustic oscillations (BAO) in the three years of observations from the Dark Energy Spectroscopic Instrument. These results, when combined with other data, have indicated a possible new anomaly in the behavior of dark energy, which has caused both excitement and consternation in the field of cosmology. I will discuss these findings and their implication for our understanding of the physics of the universe.

Informal discussion with coffee, tea, and snacks to follow.

Hosted by Professor Robert Caldwell
