NOIRLab - The First Year Results From DESI
06/08/24 • 9 min
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 Dr. Stephanie Juneau talks about the results from the first year of observations with DESI.
Bios:
Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.
Dr. 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.

Travelers in the Night Eps. 277E & 278E: Rose Rules & Disintegrating Comet
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org
Today's 2 topics:
Anyone who thinks women can't do computers and science needs to meet my Catalina Sky Survey teammate Rose Matheny. On a recent 3 night observing run at the 60 inch telescope on Mt. Lemmon, Rose took over the world of asteroid hunting when she posted 82 new potentially Earth approaching objects on the Minor Planet Center's NEO Confirmation Page. For the next several days telescopes around the world obtained additional data on Rose's discoveries. When the dust settled 29 of Rose's discoveries were proved to be Earth approaching objects, 32 are other asteroids which don't come near enough our home planet to be interesting, and the rest need more data to figure out what they are.
Comets are made up of organic materials and ices of various substance which are left over from the formation of our solar system 4.6 billion years ago. When the gravity of a nearby star or other object changes one of these dirty snowball's orbit, its path can bring it into the inner solar system and thus near enough for the Sun to affect it and for us to study what is going on.
