Will Percival talking about a new way to measure H0 (and about the @desisurvey results!) at the Cosmological Frontiers meeting @HiggsCentre @PhysAstroEd #edinburgh
Does #DarkEnergy change over time? @desisurvey scientists are exploring a mystery as big as the universe. Read the latest from @PhysicsMagazine: physics.aps.org/articles/v17/59

With new data @desisurvey, a team of scientists (including @BerkeleyLab) built the largest 3D map of the universe ever. The data hints that dark energy may not be static like previously thought, as covered in @newscientist: newscientist.com/article/242525…

ICYMI: With their first results, @desisurvey has made the biggest 3D cosmic map and world-leading measurements of #DarkEnergy! Fly through millions of galaxies mapped with DESI coordinate data in this 360-video: youtu.be/jRYUt9nE9b0?fe…
It's not a time machine, but @desisurvey has peered 11 billion years into the past and released its 1st year of data. It's the 1st time that scientists have measured the expansion of the universe in this period with this level of precision: newscenter.lbl.gov/2024/04/04/des…
Today @desisurvey announces measurements of the expanding universe - the most precise of their kind! I had to make a cake. I'm so excited to finally share our first main science results :) Press release, featuring some non-buttercream graphics I made: newscenter.lbl.gov/2024/04/04/des…
Want some help digesting the new @desisurvey results? Watch @SeshNadathur and Andreu Font Ribera talk through it all in a Cosmology Talk... 🙂 youtu.be/9DsMphPfrjI

Workshop discussing @desisurvey results? Shaun and Matthijs got you covered. Information below 👇
Attn Cosmologists! You read the DESI papers. You even watched the DESI video. But you still have questions about the analysis The miniworkshop is here for you! Featuring experts from DESI, SN, evolving DE, ν masses & more Tuesday April 16 at 18:00 UTC inspirehep.net/seminars/27765…
Don't throw out your AGN, some of us like them! A paper I was involved in, led by @StephaJuneau aims to rescue AGN from the @desisurvey BGS sample. We find 93% of the BGS-AGN sample are QSOs, with stacked spectra that look nearly identical to DESI QSOs. arxiv.org/abs/2404.03621
Let’s break down a science diagram! @desisurvey’s Hubble diagram plots a characteristic pattern – baryon acoustic oscillations, or BAO “bubbles” – at different ages of the universe. Read the full explanation here: newscenter.lbl.gov/2024/04/04/des… #DarkEnergy Credit: Claire Lamman/DESI

It's not a time machine, but @desisurvey has peered 11 billion years into the past and released its 1st year of data. It's the 1st time that scientists have measured the expansion of the universe in this period with this level of precision: newscenter.lbl.gov/2024/04/04/des…
**8** years ago I was on @KittPeakNatObs to make a giant image mosaic for @desisurvey. This project still is a big part of not just my work but my life due to all the time and energy poured into it. And yet I'm just one out of so many people working tirelessly to make it happen🔭
👀👀👀 Definitely no smoking gun, but a tantalizing hint in this first @desisurvey release. Evolving dark energy over time would be HUGE!
Our BAO measurements agree with Planck ΛCDM (solid line), but indicate a slight preference for evolving dark energy (dashed line) instead of the standard cosmological constant Λ. 5/10 📸 Credit: Arnaud de Mattia, CEA Saclay
