About DESI

The Dark Energy Spectroscopic Instrument (DESI) is a cosmological survey that aims to map the large-scale structure of the universe and understand the nature of dark energy. It will measure the spectra of millions of galaxies and quasars, that the DESI scientists will analyse to constrain the cosmological models that describe the evolution of the universe.

DESI is a collaboration of scientists and engineers from around the world, working together to build and operate a state-of-the-art spectrograph at the Mayall Telescope in Arizona.

Learn more about DESI

Le Dark Energy Spectroscopic Instrument (DESI) est un projet cherche à cartographier la structure à grande échelle de l’univers et à comprendre la nature de l’énergie noire. Il mesurera les spectres de millions de galaxies et de quasars, que les scientifiques de DESI analyseront pour contraindre les modèles cosmologiques qui décrivent l’évolution de l’univers.

DESI est une collaboration de scientifiques et d’ingénieurs du monde entier, travaillant ensemble pour construire et exploiter un spectrographe de pointe au télescope Mayall en Arizona.

About DESI High

DESI High is an outreach initiative that aims to bring the excitement of cosmology and astrophysics to high school students (and older). It provides a set of resources, including notebooks, videos, and other educational materials, to help students learn about the universe and the science behind DESI. By using real DESI data, students can explore the universe, learn how to analyse astronomical data, and develop programming skills.

À propos de DESI High

DESI High est une initiative visant faire découvrir l’astronomie et la science des données aux lycéens (et plus) du monde entier. Elle fournit des ressources, incluant des notebooks, des vidéos et d’autres supports pour aider les étudiants à en apprendre plus sur l’univers et la science derrière DESI. En utilisant les données réelles de DESI, les étudiants peuvent explorer l’univers, apprendre à analyser des données astronomiques et développer des compétences en programmation.

Rochester, United States

I’m Hernan, a PhD student at the University of Rochester in the United States. I study the emptiest regions of the universe known as cosmic voids where there are relatively few galaxies. I enjoy giving public talks about DESI science and giving tours of my university’s local astronomical observatory. In my free time, I write short stories and novels.

Hi! I am Otávio Alves, a PhD student at the University of Michigan in the United States. I work on calculating the uncertainties of DESI observables (covariance matrices!), which are part of the galaxy clustering analysis. I find great joy in developing interactive tools that allow people to experience science at any level of expertise. Outside of research, I spend my time playing music, reading or designing electronic gadgets.
