New data from DESI is a goldmine for observational cosmology

Tuesday, November 19, 2024

Building off the first analyses of the largest 3D map of the universe released earlier this year, scientists working with the Dark Energy Spectroscopic Instrument (DESI) have pulled additional information from the map.  

DESI observatory telescope

DESI is an international collaboration of more than 900 researchers from over 70 institutions around the world, including a strong presence at the University of Waterloo, and is managed by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory. 

Waterloo’s team is led by Dr. Will Percival, Director of the Waterloo Centre for Astrophysics (WCA) and co-Spokesperson for DESI, leading the international team of scientists analysing the DESI data. The team at Waterloo, which also includes Dr. Alex Krolewski, a postdoctoral fellow at the WCA, and former graduate student Siddhardha Penmetsa, worked to check for inconsistencies based on the way the spectra of the galaxies were taken.
