🔊 New BAO analysis from the 3-year observations (DR2). Long story short, as follows.
1. DESI alone is consistent with LCDM. 👉 Boring
2. DESI and Planck have a 2.3 discrepancy in Ωm-H0rd plane. 👉Interesting.

📢In less than 24h, @desisurvey.bsky.social will present the 3D BAO analysis of its first 3yr of data (DR2), the BAO analysis of the largest sample of galaxies ever!!! And we will release all DR1 catalogues (1yr of data) as well. You will find all the details on arXiv and SM channels. Stay tuned. 🎶
At the same time, we’re also releasing exciting new results, including BAO measurements from galaxies, quasars, and Lyman-alpha forests.
🔗 Info about these results will be available on the DESI website: desi.lbl.gov

🥁Paper Day! Here goes the first bispectrum analysis of the @desisurvey.bsky.social DR1 LRG and QSO data, led by my PhD student Sergi Novell at @icc-ub.bsky.social. In combination with the power spectrum multipoles we measure 150 triangle configurations corresponding to a total volume of 13.1 Gpc3

The US government has been turned over to a group of extraordinarily ignorant people, and they are working to destroy science in this country. Cutting over half the NSF budget would save < 0.1% of the federal budget, but do incalculable harm. Simply heartbreaking.

White House budget proposal could shatter the National Science Foundation
“This kind of cut would kill American science and boost China.”…

Cosmology Talks: Recent DESI Power Spectrum Results
Some weeks ago I posted an item about recent results that have emerged from the DESI (Dark Energy Spectroscopic Instrument) Collaboration. I have been a bit busy since then but I just saw that there is one of those Cosmology Talks about these results which I thought I would pass on. The contributors are Arnaud de Mattia, Hector Gil-Marín and Pauline Zarrouk and they are talking about the analsysis they have done using the "full shape" of the galaxy power spectrum. It's quite a long video, but very illuminating.
