My first night at the observatory, I walked outside and was amazed at how clear Orion was. As my eyes adapted to the dark, something more amazing happened: I had trouble finding Orion amongst so many stars. And to think, DECam finds even more objects than that in the sky! #dest4td

(Keen observers from the Northern Hemisphere may notice that Orion looks a bit different in this image from Chile! We're used to seeing the 'belt' be above the Orion Nebula.)

Thank you to Ann Eliott (The Ohio State University) for today's thought for the day! ... See MoreSee Less

Cosmology Results from The Dark Energy Survey!

August 14, 2017 12:00 am

With CMB telescopes vastly expanding our understanding of the early universe the past two decades, it was only a matter of time before we gained the capability to perform a census of the millions of galaxies at our disposal today using ground based telescopes. This is a very important step: studying today’s galaxies tells us whether the universe evolved after the CMB the way we think it did. Today’s bite is not just about thanking the early universe for being kind in its evolution, but also an ode to the 400+ scientists working over the last two decades to bring this census to fruition!

Dark Energy Survey reveals most accurate measurement of dark matter structure in the universe

August 8, 2017 12:00 pm

Imagine planting a single seed and, with great precision, being able to predict the exact height of the tree that grows from it. Now imagine traveling to the future and snapping photographic proof that you were right. If you think of the seed as the early universe, and the tree as the universe the way it looks now, you have an idea of what the Dark Energy Survey (DES) collaboration has just done. In a presentation today at the American Physical Society Division of Particles and Fields meeting at the U.S. Department of Energy’s (DOE) Fermi National Accelerator Laboratory, DES scientists will unveil the most accurate measurement ever made of the present large-scale structure of the universe.

DES Year 1 Cosmology Results: Papers

August 8, 2017 11:30 am

This page serves as the portal for a series of 10 papers on and in support of the DES cosmology results from the first year (Y1) of the survey, which were released on Aug. 3, 2017. For each paper, clicking on ‘Link’ will take you to the arXiv, where the pdfs can be accessed. On Thurs., Aug. 3, 2017, Daniel Gruen delivered a talk on these results at the APS Division of Particles & Fields meeting at Fermilab. A video of this talk as well as the slides can be accessed via the page link.

Dark Energy Survey: Most Accurate Map of Recent Universe Unveiled by Scientists

August 8, 2017 11:29 am

A new map of the universe has been unveiled by scientists, revealing the last seven billion years of the history of the cosmos. The results of the Dark Energy Survey show how dark matter is distributed across the galaxy. Until now, scientists used models to show where it fell. These models are largely based the Standard Model of particle physics, the incomplete theory that best explains how matter across the universe interacts.
