The Dark Energy Survey

The Dark Energy Survey (DES) is an optical/near-infrared survey that aims to probe the dynamics of the expansion of the Universe and the growth of large scale structure. The collaboration is composed of research institutions and universities from the United States, Brazil, the United Kingdom, Germany, Spain, and Switzerland.

The survey uses the 4-meter Victor M. Blanco Telescope located at Cerro Tololo Inter-American Observatory (CTIO) in Chile, outfitted with the newly designed, state-of-the-art Dark Energy Camera (DECam). This camera allows for more sensitive images in the red part of the visible spectrum and in the near infrared, in comparison to previous instruments.

DECam has one of the widest fields of view (2.2-degree diameter) available for ground-based optical and infrared imaging. The survey will image 5,000 square degrees of the southern sky in a footprint that overlaps with the South Pole Telescope and Stripe 82 (in large part avoiding the Milky Way). The survey will take five years to complete, and the survey footprint will nominally be covered te times in five photometric bands (g, r, i, z, and Y). DES officially began in August 2013 and completed its second season in February 2015.

Dark energy

In physical cosmology and astronomy, dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe. Dark energy is the most accepted hypothesis to explain the observations since the 1990s indicating that the universe is expanding at an accelerating rate. Assuming that the standard model of cosmology is correct, the best current measurements indicate that dark energy contributes 68.3% of the total energy in the present-day observable universe. The mass–energy of dark matter and ordinary (baryonic) matter contribute 26.8% and 4.9%, respectively, and other components such as neutrinos and photons contribute a very small amount. Again on a mass–energy equivalence basis, the density of dark energy (~ 7 × 10⁻³⁰ g/cm³) is very low, much less than the density of ordinary matter or dark matter within galaxies. However, it comes to dominate the mass–energy of the universe because it is uniform across space.

Two proposed forms for dark energy are the cosmological constant, a constant energy density filling space homogeneously, and scalar fields such as quintessence or moduli, dynamic quantities whose energy density can vary in time and space. Contributions from scalar fields that are constant in space are usually also included in the cosmological constant. The cosmological constant can be formulated to be equivalent to vacuum energy. Scalar fields that do change in space can be difficult to distinguish from a cosmological constant because the change may be extremely slow.

Dark Energy (album)

Dark Energy is the debut album of Indiana producer Jlin, released in 2015 by Planet Mu. It received acclaim from critics, and was named the best album of 2015 by The Wire and The Quietus.

Critical reception

Dark Energy received universal acclaim from music critics.AllMusic called it "simply one of the most compelling debut albums of 2015," describing it as "tense, thrilling, and a bit frightening."The Quietus wrote that "In its breadth of ambition and stunningly realised sounds, Dark Energy delivers more than just a new twist on an established style [...] it maps out an inspiring and tantalising glimpse of electronic music's future." Referring to the producer's roots in the Chicago dance style known as footwork, The Guardian wrote "Jlin is an artist who belongs to her genre, but has an eye on where it could go next." Resident Advisor stated that "Jlin has plenty to say, and she has a remarkably strong and distinctive voice with which to say it."

  Exploring 7 billion light years of space with the Dark Energy Survey

  The Dark Energy Survey tackles big questions about our universe: What is it made of? How is matter distributed? How has the universe evolved? And what roles do dark matter and dark energy play? To address these puzzles, the experiment uses a powerful 570-megapixel camera to photograph galaxies close to home and billions of light years away. The analysis of the first three years of data resulted in the largest maps ever made showing the distribution and shapes of galaxies in our universe – and provided a fantastic test for scientist’s best predictions.

  The Dark Energy Survey Supernova Program - Data and Cosmology (Davis, Vincenzi and Brout)

  Cosmology from Home registration: https://cosmologyfromhome.com/registration/ Tamara Davis, Maria Vincenzi and Dillon Brout tell us about the Dark Energy Survey's (DES) new supernova catalogue. The catalogue has more than 1500 new supernovae, and will allow a vast range of new cosmology constraints. It is a factor of around five larger than the next largest high redshift supernovae catalogue. Very curiously, DES' supernovae see hints of evolving dark energy. This is especially curious given that a few months after DES released this data, the Dark Energy Spectroscopic Instrument (DESI) also released data with similar hints.

The Dark Energy Survey tackles big questions about our universe: What is it made of? How is matter distributed? How has the universe evolved? And what roles do dark matter and dark energy play? To address these puzzles, the experiment uses a powerful 570-megapixel camera to photograph galaxies close to home and billions of light years away. The analysis of the first three years of data resulted in the largest maps ever made showing the distribution and shapes of galaxies in our universe – and provided a fantastic test for scientist’s best predictions.

Cosmology from Home registration: https://cosmologyfromhome.com/registration/ Tamara Davis, Maria Vincenzi and Dillon Brout tell us about the Dark Energy Survey's (DES) new supernova catalogue. The catalogue has more than 1500 new supernovae, and will allow a vast range of new cosmology constraints. It is a factor of around five larger than the next largest high redshift supernovae catalogue. Very curiously, DES' supernovae see hints of evolving dark energy. This is especially curious given that a few months after DES released this data, the Dark Energy Spectroscopic Instrument (DESI) also released data with similar hints.

RAS March Public Talk - Dr Alexandra Amon Unveiling the Dark Universe with the Dark Energy Survey In her Caroline Herschel Prize Lecture entitled “Unveiling the Dark Universe with the Dark Energy Survey”, Dr Amon will describe some of the mind-blowing historical moments leading to the paradigm-change, the challenges in the field, the Dark Energy Survey and its results, including the experimental process - from nights at the remote telescope to hurdles in the data analysis. The conclusions will guide the audience to appreciate current mysteries and future directions. About our speaker Dr Amon is an expert in cosmology. She is a Senior Kavli Fellow at the Institute for Cosmology and a Senior Postdoctoral Researcher at Trinity College at the University of Cambridge. Before this, she was a Fellow at Stanford University and the SLAC National Accelerator Laboratory. She obtained her Masters degree and PhD at the University of Edinburgh in 2018 and has numerous awards, such as the Michael Penston Thesis Prize/Fermilab Tollestrup Award. Dr Amon is co-coordinator of the Weak Lensing group of the worldwide collaboration “The Dark Energy Survey”, including over 100 members. Dr Amon uses observational data for over 100 million galaxies and a technique called ‘gravitational lensing’ in order to test the Standard Cosmological Model. The intriguing results she and her collaborators find hint at cracks in the currently accepted model for our Universe, which is mostly dark, with over 95 percent of it in the form of dark energy and dark matter, whose natures are the biggest mysteries in modern physics. Dr. Amon was the Caroline Herschel Prize Lectureship Winner in 2022 The Caroline Herschel Prize Lectureship was established in 2018 by what is now the Herschel Society, in association with the Royal Astronomical Society, to celebrate Caroline’s memory by supporting promising women astronomers early in their careers. Caroline, William’s younger sister, started out as his assistant, but in time became recognised as an important astronomer in her own right, was the first to be paid as such, and was awarded the RAS Gold Medal in 1828. The Caroline Herschel Prize Lecture is hosted by University of Bath in November in cooperation with the Society as part of the University’s public lecture series.

Join world-leading scientist Ofer Lahav as he reveals the narrative of the Dark Energy Survey (DES), an ambitious experiment designed to unravel the mysteries of the force shaping our universe. Watch the Q&A here (exclusively for our Science Supporters): Discover what the 3D map spanning 300 million galaxies and extensive supernovae has so far revealed, including its confirmation of the prevailing model of cold dark matter and a remarkably accurate cosmological constant. But this remarkable survey doesn’t just advance our scientific understanding – Ofer sheds light on the human dimension of this project, sharing anecdotes of the long-term commitment and collaboration of the hundreds of scientists involved and the resilience they’ve shown in overcoming challenges along the way. Join Ofer to explore the global nature of scientific progress, where teamwork and perseverance shape groundbreaking discoveries. The DES not only helps to reveal the mysteries of dark energy but also highlights the collective dedication and collaborative spirit that fuels scientific exploration. --- Ofer Lahav holds the Perren Chair of Astronomy at University College London (UCL) and is Vice-Dean (International) of the UCL Faculty of Mathematical and Physical Sciences (MAPS). Additionally, he co-directs the STFC Centre for Doctoral Training in Data Intensive Science. Specialising in Observational Cosmology, Lahav focuses on probing Dark Matter and Dark Energy, utilising Machine Learning for Big Data applications. Having served as the Head of Astrophysics at UCL from 2004 to 2011 and as Vice-Dean (Research) of UCL's Faculty of Mathematical and Physical Sciences from 2011 to 2015, Oher has played key roles in academic leadership. He served as Vice-President of the Royal Astronomical Society from 2010 to 2012 and played a pivotal role in founding the Dark Energy Survey (DES). His multi-faceted roles and groundbreaking research highlight his commitment to advancing the field of observational cosmology and understanding the fundamental properties of the universe. --- The Ri is on Twitter: http://twitter.com/ri_science and Facebook: http://www.facebook.com/royalinstitution and TikTok: https://www.tiktok.com/@ri_science Listen to the Ri podcast: https://podcasters.spotify.com/pod/show/ri-science-podcast Donate to the RI and help us bring you more lectures: https://www.rigb.org/support-us/donate-ri Our editorial policy: https://www.rigb.org/editing-ri-talks-and-moderating-comments Subscribe for the latest science videos: http://bit.ly/RiNewsletter Product links on this page may be affiliate links which means it won't cost you any extra but we may earn a small commission if you decide to purchase through the link.

The Dark Energy Survey tackles big questions about our universe: What is it made of? How is matter distributed? How has the universe evolved? And what roles do dark matter and dark energy play? To address these puzzles, the experiment uses a powerful 570-megapixel camera to photograph galaxies close to home and billions of light years away. The analysis of the first three years of data resulted in the largest maps ever made showing the distribution and shapes of galaxies in our universe – and provided a fantastic test for scientist’s best predictions.

Prior to the discovery, only two dozen or so stellar streams were known, many of which were discovered in data from a precursor survey, the Sloan Digital Sky Survey (SDSS).” Dark Energy Survey Finds New Stellar Streams Destroyed by the Milky Way https://www.seeker.com/astronomy/dark-energy-survey-finds-new-stellar-streams-destroyed-by-the-milky-way “A project designed to help uncover the nature of dark energy and dark matter in our universe has found that alien stars from other galaxies have been infiltrating the Milky Way. The Dark Energy Survey has found 11 new streams of stars that do not originate from our own galaxy.” Astronomers Found Two Massive Galaxies Amid an Ocean of Dark Matter https://www.seeker.com/astronomy/astronomers-found-two-massive-galaxies-amid-an-ocean-of-dark-matter “Astronomers have found a pair of surprisingly gigantic galaxies from the early universe, and one is the most massive galaxy ever seen from when the universe was young. Observations show the pair of big galaxies existed less than 800 million years after the Big Bang, and their size doesn’t conform to current cosmological models, which say early galaxies were much smaller than today’s galaxies.” ____________________ Seeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.

Cosmology from Home registration: https://cosmologyfromhome.com/registration/ Tamara Davis, Maria Vincenzi and Dillon Brout tell us about the Dark Energy Survey's (DES) new supernova catalogue. The catalogue has more than 1500 new supernovae, and will allow a vast range of new cosmology constraints. It is a factor of around five larger than the next largest high redshift supernovae catalogue. Very curiously, DES' supernovae see hints of evolving dark energy. This is especially curious given that a few months after DES released this data, the Dark Energy Spectroscopic Instrument (DESI) also released data with similar hints.

RAS March Public Talk - Dr Alexandra Amon Unveiling the Dark Universe with the Dark Energy Survey In her Caroline Herschel Prize Lecture entitled “Unveiling the Dark Universe with the Dark Energy Survey”, Dr Amon will describe some of the mind-blowing historical moments leading to the paradigm-change, the challenges in the field, the Dark Energy Survey and its results, including the experimental process - from nights at the remote telescope to hurdles in the data analysis. The conclusions will guide the audience to appreciate current mysteries and future directions. About our speaker Dr Amon is an expert in cosmology. She is a Senior Kavli Fellow at the Institute for Cosmology and a Senior Postdoctoral Researcher at Trinity College at the University of Cambridge. Before this, she was a Fellow at Stanford University and the SLAC National Accelerator Laboratory. She obtained her Masters degree and PhD at the University of Edinburgh in 2018 and has numerous awards, such as the Michael Penston Thesis Prize/Fermilab Tollestrup Award. Dr Amon is co-coordinator of the Weak Lensing group of the worldwide collaboration “The Dark Energy Survey”, including over 100 members. Dr Amon uses observational data for over 100 million galaxies and a technique called ‘gravitational lensing’ in order to test the Standard Cosmological Model. The intriguing results she and her collaborators find hint at cracks in the currently accepted model for our Universe, which is mostly dark, with over 95 percent of it in the form of dark energy and dark matter, whose natures are the biggest mysteries in modern physics. Dr. Amon was the Caroline Herschel Prize Lectureship Winner in 2022 The Caroline Herschel Prize Lectureship was established in 2018 by what is now the Herschel Society, in association with the Royal Astronomical Society, to celebrate Caroline’s memory by supporting promising women astronomers early in their careers. Caroline, William’s younger sister, started out as his assistant, but in time became recognised as an important astronomer in her own right, was the first to be paid as such, and was awarded the RAS Gold Medal in 1828. The Caroline Herschel Prize Lecture is hosted by University of Bath in November in cooperation with the Society as part of the University’s public lecture series.

The Dark Energy Survey

The Dark Energy Survey (DES) is an optical/near-infrared survey that aims to probe the dynamics of the expansion of the Universe and the growth of large scale structure. The collaboration is composed of research institutions and universities from the United States, Brazil, the United Kingdom, Germany, Spain, and Switzerland.

The survey uses the 4-meter Victor M. Blanco Telescope located at Cerro Tololo Inter-American Observatory (CTIO) in Chile, outfitted with the newly designed, state-of-the-art Dark Energy Camera (DECam). This camera allows for more sensitive images in the red part of the visible spectrum and in the near infrared, in comparison to previous instruments.

DECam has one of the widest fields of view (2.2-degree diameter) available for ground-based optical and infrared imaging. The survey will image 5,000 square degrees of the southern sky in a footprint that overlaps with the South Pole Telescope and Stripe 82 (in large part avoiding the Milky Way). The survey will take five years to complete, and the survey footprint will nominally be covered te times in five photometric bands (g, r, i, z, and Y). DES officially began in August 2013 and completed its second season in February 2015.
