And, of course, have a look at our paper at https://t.co/CSQOAWTYjb ! 3/3

I had a fun conversation with @kgvancamp about my new Web-Halo Model (WHM) on The Space Between podcast https://t.co/KehtG85QbJ and its connections to a map of Kansas, meatballs, honeycombs, spinning tops, and more! 1/3

[Samuel Brieden @Cosmosamu]

Tune in and learn how the WHM precisely describes structure formation towards about 5x smaller scales than standard, perturbative methods, allowing us to squeeze out much more cosmological information from galaxy survey data! 2/3

🚨 BIG NEWS ALERT! 🚨
We’re just 24 HOURS AWAY from a MAJOR DESI release! 🌉🔭

Tomorrow at 3 PM PT, DESI is unveiling DR1, our first official Data Release—the largest dataset of its kind, packed with information on 18.7 million galaxies, quasars, and stars! But that’s not all…

[DESI Survey @desisurvey]

In its quest to make precision cosmological measurements, DESI uses a process called “blinding” in its analysis methodology in order to avoid the inaccuracies that can arise from confirmation bias.

[DESI Survey @desisurvey]

🎉DESI released another set of papers based on Y1 data. These new results provide an extended, “full-shape” analysis of the Y1 data by looking at how galaxies and quasars cluster on different scales, both in the plane of the sky and along the line of sight in redshift space.

[Berkeley Lab @BerkeleyLab]

.@desisurvey scientists mapped how nearly 6 million galaxies cluster across 11 billion years of cosmic history. Their observations line up with what Einstein's theory of general relativity predicts.

We are excited to present the new power spectrum Full-Shape results on DESI DR1 data @desisurvey. Check all the new papers at https://t.co/zeTynP4tV6. A thread🧵👇

[Physics Astro @ Edin @PhysAstroEd]

Is the way in which galaxies cluster consistent with our understanding of the standard model of gravity and the predictions from Einstein's theory of General Relativity? 🔭

A new study from the @DESIsurvey is one of the most stringent tests yet of general relativity and how #gravity behaves at cosmic scales. Read the latest: https://t.co/A4QuPHEMXC

[Héctor Gil Marín @cosmonautic0]

Paper day📢. Sergi Novell-Masot has demonstrated how the catalogue-level blinding technique used for @desisurvey also works for higher-order statistics📐, showing how this technique consistently blinds all summary statistics of interest coherently.

I was honoured with the opportunity to present my PhD work at the SEA meeting in Granada today!

[Héctor Gil Marín @cosmonautic0]

Congratulations to @Cosmosamu for his best thesis @SEA_astronomia prize. Today Sam recieved it and gave a fantastic introductory talk about his work within the @desisurvey at the #RCSEA2024.

[DESI Survey @desisurvey]

Paper day! Again! 🎉 Yesterday we released a batch of supporting papers in prep (analysis applied to simulations only) for the full-shape analysis yet to come, and also presenting and validating our blinding scheme. Find the papers and explanations at https://t.co/fGmMkZ0lpV. 1/2
