Dark Energy Survey

From Scientific American, Jan. 30, 2019: Fermilab scientist Antonella Palmonese weighs in on a new method of determining the Hubble constant. The method uses data taken from the Fermilab-hosted Dark Energy Survey.

From Nature Reviews Physics, Jan. 28, 2019: The Dark Energy Survey completed its six-year-mission to map more than 300 million distant galaxies; however, an equally arduous task — analyzing the acquired 50 terabytes of data with a view to understanding the expansion of the universe — is just beginning.

From APS’s Physics, Jan. 29, 2019: On Jan. 9, a handful of researchers with the Dark Energy Survey — one of the most ambitious attempts to probe the dynamics of the universe’s expansion — headed to the control room of Chile’s Blanco Telescope. For one last time, they opened the white telescope’s dome. From their perch overlooking the red Andean Mountains, they set up for a night of observing the southern sky.

From WDCB’s First Light, Jan. 20, 2019: This WDCB interview features Fermilab scientists Brenna Flaugher and Tom Diehl talking about the final nights of the Dark Energy Survey.

From Sinc, Jan. 15, 2019: Tras seis años captando millones de galaxias con una cámara del telescopio Blanco, la colaboración científica Dark Energy Survey ha completado el cartografiado de un octavo del cielo con un detalle sin precedentes. Los resultados ya han servido para publicar más de 200 artículos científicos, pero se esperan muchos más, con el objetivo puesto en descubrir la naturaleza de la misteriosa energía oscura.

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 Republica, 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.

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 insideHPC, Jan. 9, 2019: After scanning in depth about a quarter of the southern skies for six years and cataloging hundreds of millions of distant galaxies, the Dark Energy Survey finishes taking data on Jan. 9. The National Center for Supercomputing Applications at the University of Illinois will continue refining and serving this data for use by scientists into 2021.
