New Results from DESI
I’ve just got time between meetings to mention that a clutch of brand new papers has emerged from the DESI (Dark Energy Spectroscopic Instrument) Collaboration. There is a press release discussing the results from the Lawrence Berkeley Laboratory here and one from the ICCUB in Barcelona here; several members of the group I visited there during sabbatical are working on DESI. Congratulations to them.
I haven’t had time to read them yet, but a quick skim suggests that the results are consistent with the standard cosmological model.
The latest batch contains three Key Publications:
- DESI Collaboration et al., DESI 2024 II: Sample Definitions, Characteristics, and Two-point Clustering Statistics
- DESI Collaboration et al., DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars
- DESI Collaboration et al., DESI 2024 VII: Cosmological Constraints from the Full-Shape Modeling of Clustering Measurements
together with the companion supporting papers:
- Ishak et al. (2024), Modified Gravity Constraints from the Full Shape Modeling of Clustering Measurements from DESI 2024
- Rosado-Marín et al. (2024), Mitigating Imaging Systematics for DESI 2024 Emission Line Galaxies and Beyond
- Bianchi et al. (2024), Characterization of DESI fiber assignment incompleteness effect on 2-point clustering and mitigation methods for Y1 analysis
- Forero-Sánchez et al. (2024), Analytical and EZmock covariance validation for the DESI 2024 results
- Findlay et al. (2024), Exploring HOD-dependent systematics for the DESI 2024 Full-Shape galaxy clustering analysis
The links lead to the arXiv version of these papers. These articles can also be found, along with previously released publications by the DESI Collaboration, here.

Peter, I am unable to read the comments on google chrome on a Mac

There are no comments on this post on this site (apart from yours and this reply). Some time ago I set up the blog as a federated site (part of the “fediverse”). This means that my posts appear in full on other websites including the social media platform Mastodon. Readers can comment on WordPress as usual, or on one of these other sites. If someone comments on WordPress you see the comment as previously, but if someone comments elsewhere in the fediverse it doesn’t come back to WordPress. This explains why you see only some of the comments. You may see that there are n comments, but if none of those were actually posted here then you won’t see any here.
