NOIR Lab - DESI’s Year 3 Results

Hosted by Rob Sparks.


Description: The Dark Energy Spectroscopic Instrument (DESI) at
Kitt Peak National Observatory has been collecting spectra of
millions of galaxies to better understand dark energy, the
mysterious force that is causing the expansion of the universe to
accelerate. The DESI collaboration recently released results
based on the first three years of data that indicate dark energy
is not a constant force. In this podcast, NOIRLab’s Joan Najita
discusses DESI and its groundbreaking results.

Rob Sparks is in the Communications, Education
and Engagement group at NSF’s NOIRLab in Tucson, Arizona.


Dr. Joan Najita is an astronomer at NOIRLab,
NSF’s research and development center for ground-based optical
and infrared astronomy. She studies the origins of stars and
planets and the life histories of the Milky Way and nearby
galaxies. A long-time advocate for "highly multiplexed
spectroscopy" (i.e., facilities like DESI), she also studies how
discoveries are made in astronomy, and works to develop new tools
and facilities that sustain discovery.
