30 July 2026 Wynne Turner (Ohio State) The Key Paper released today presents new measurements from the full distribution of hydrogen gas traced by the Lyman-alpha forest, yielding the most precise cosmological constraints from this probe to date. Background The quasars observed by DESI emitted the light we see today around 11 billion years ago. […]
by Nico Schuster (CPPM) 7 July 2026 When we look at the positions of the millions of galaxies DESI has measured, one thing jumps out immediately: galaxies are not spread out evenly. Instead, they clump and string together into a cosmic web: bright filaments of galaxies threaded around huge, almost empty voids, which are some […]
What is your position or role in the DESI project? Since November 2025, I have been one of the two co-leads of the Alternative Clustering Methods (ACM) topical group within the Galaxy and Quasar Clustering working group in DESI. Where were you born? I was born and raised in Greece, in a town called Trikala. […]
What is your position or role in the DESI project? I am currently co-chair of the primordial non-Gaussianity (PNG) topical group. My previous work has largely focused on cross-correlations of DESI galaxies with cosmic microwave background (CMB) data, which will be incorporated into future DESI PNG analyses to better constrain the initial conditions of our […]
What is your position or role in the DESI project? I have been an active member of the DESI Cosmology and BAO Key Project teams, and for over three years I co-chaired the Cosmological Parameter Estimation (CPE) working group. I have also served on the meetings and membership committees, and I am currently a member […]
What is your position or role in the DESI project? I am a topical group co-lead for the 2pt+3pt key project Where were you born? In the south of Germany (Waiblingen) Where do you live now? In Edinburgh, Scotland What do you do as part of DESI? I am mainly coordinating the 2pt+3pt topical group […]
What is your position or role in the DESI project? I am currently a co-lead of the HOD Topical Group in GQP Working Group. Modeling galaxy-halo connection for DESI tracers is one of the most important model ingredients for a realistic high-fidelity synthetic simulation that can be of a wide use and interest among DESI. […]
What is your position or role in the DESI project? I currently co-lead the Year 2 data release full-shape analysis using the 2-point and 3-point statistics. I am also a member of the DESI Publication Board. Where were you born? Shanghai, China Where do you live now? Munich, Germany What do you do as part […]
What is your position or role in the DESI project? I am a PhD student at Sorbonne Univerité in Paris. I work with my supervisor Pauline Zarrouk at the Laboratoire de Physique Nucléaire et de Hautes Énergies (LPNHE). I am involved with the Alternative Clustering methods topical group, where we try to apply new analysis methods […]
Follow up of Rubin Alerts Characterizes the Transient Sky 4 May 2026 Joan Najita (NOIRLab) With its large field of view and ability to acquire a lot of spectra simultaneously, DESI is well suited to many investigations beyond its primary mission of charting out the role of dark energy in the expansion history of the […]
