dark energy

From 365 Days of Astronomy, Jan. 12, 2019: The Dark Energy Survey is the subject of this 30-minute podcast. DES started in 2013 to map dark energy over 5000 square degrees of sky. It used a massive 500-megapixel camera attached to the Blanco Telescope at Cerro Tololo Inter-American Observatory in Chile. The survey concluded on Jan. 9, 2019, with its last night of observing. At the American Astronomical Society meeting in Seattle, they conferenced with observers on the last night. Listen to the conversation at the end of this journey.

From University of Chicago, Jan. 9, 2019: After scanning about a quarter of the southern skies over 800 nights, the Dark Energy Survey finished taking data on Jan. 9. It ends as one of the most sensitive and comprehensive surveys of its kind, recording data from more than 300 million distant galaxies. Fermilab, an affiliate of the University of Chicago, served as lead laboratory on the survey, which included more than 400 scientists and 26 institutions.

From, El Dia, Jan. 9, 2019: El trabajo fue po astrofísicos del proyecto Dark Energy Survey, tras seis años de observación en los que acumularon información de más de 300 millones de galaxias lejanas.

From estrella digital, Jan. 9, 2019: Los astrofísicos que han participado en el proyecto Dark Energy Survey han finalizado hoy la toma de datos para cartografiar con un detalle sin precedentes una octava parte del cielo, tras seis años de trabajos en los que han acumulado datos de más de 300 millones de galaxias lejanas.

After scanning in depth about a quarter of the southern skies for six years and cataloguing hundreds of millions of distant galaxies, the Dark Energy Survey will finish taking data on Jan. 9. DES scientists recorded data from more than 300 million distant galaxies. More than 400 scientists from over 25 institutions around the world have been involved in the project, hosted by Fermilab. The collaboration has already produced about 200 academic papers, with more to come.

From Berkeley Lab, Dec. 4, 2018: Key components of Berkeley Lab’s Dark Energy Spectroscopic Instrument are installed after months of planning, prep work. A team at Fermilab built the corrector, hexapod, and other top-end support structures. The structures are designed to align the lenses with an accuracy of tens of microns (millionths of a meter) – similar to the width of the thinnest human hair.

Our best model of particle physics explains only about 5 percent of the universe.

From CNN, Aug. 17, 2018: Fermilab scientist Don Lincoln discusses the conflict between superstring theory and the phenomenon of dark energy, mentioning the Dark Energy Survey.

DESI, an instrument to help scientists get to the bottom of the dark energy mystery, is getting a little help from Fermilab.

From UQ News, Aug. 1, 2018: A scientist from the Dark Energy Survey, which is hosted by Fermilab, is selected for the television program Australian Survivor.
