From 365 Days of Astronomy, Feb. 9, 2019: In this podcast, The Dark Energy Survey started in 2013 to map dark energy over 5000 square degrees of sky. Writer and poet Amy Catanzano visited Cerro Tololo Inter-American Observatory during the Dark Energy Survey. In this podcast, Amy discusses her work in quantum poetics, her experience with the Dark Energy Survey and shares some of her poetry.

The discovery of gravitational waves, predicted by Einstein in 1916, is now enabling important tests of the theory of general relativity, as well as beginning multimessenger astronomy: the combined observations of astrophysical phenomena using electromagnetic radiation, gravitational waves and neutrinos. Barish will explore plans and prospects for gravitational-wave science.

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 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.
