DESI 2024 in the News: Science Communicators Discuss the Cosmology Results from DESI’s Inaugural Year
DESI 2024 in the News: Is Dark Energy Weakening? New Uncertainty Invites Optimism About the Fate of the Universe
Description:
Dark energy is a mysterious force that is causing the expansion of the universe to accelerate. The Dark Energy Spectroscopic Instrument (DESI) attached to the Nicholas U. Mayall Telescope at Kitt Peak National Observatory is currently measuring the redshifts to tens of millions of galaxies to help unravel the mystery of dark energy. In this podcast, NOIRLab’s Stephanie Juneau talks about the results from the first year of observations with DESI.
Bio: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona
Stephanie Juneau is an astronomer at NSF NOIRLab, and a data scientist for the Astro Data Lab. She obtained her BSc and MSc in physics from the Université de Montréal, and her PhD from the University of Arizona in 2011. She then moved to CEA-Saclay in France, where she started as a Marie Curie fellow before becoming staff researcher in 2012. She moved back to Tucson, Arizona in 2016 to join the scientific staff at NSF NOIRLab.
Dr. Juneau’s expertise lies primarily in the field of supermassive black hole and galaxy evolution. She is interested in answering questions about the growth of galaxies and that of the black holes that reside in their centers, as well as the interplay between the two. Her work brings together multiwavelength observations, close comparison with numerical simulations, and ranges from detailed case studies to statistical analysis of large datasets. As a member of the DESI and Euclid collaborations, she is particularly excited about leveraging millions of galaxy and quasar spectra to further our understanding of the black hole-galaxy connection and expand to larger scales.
