The Dark Energy Survey

The New Horizons probe recently (2015) performed a flyby of the Pluto’s system, giving us an unprecedented view of this dwarf planet and satellites.

However, we cannot send probes to every rock in the cold depths of our solar system. By observing the silhouette of solar system bodies against bright stars, a technique called occultation, we can learn a lot about them.

However, predicting when a small rock, far away from us, will cross the light path of a star for an Earth-based observer requires accurate astrometry, the technique to measure the position of celestial bodies.

DES helps us with fresh and precise astrometry of Trans Neptunian Objects (TNOs - those beyond the orbit of Neptune) allowing us to refine their orbits, predict occultations, and then measure sizes, shapes, detect ring systems and faint atmospheres when they exist. www.nasa.gov/mission_pages/newhorizons/main/index.html #DEST4TD -- Julio Camargo (DES Brazil) ...

Penn physicists study galaxies to solve mysteries of dark matter

April 20, 2017 12:00 am

In the 1970s, scientists noticed something strange about the motion of galaxies. All the matter at the edges of spiral galaxies was rotating just as fast as material in the inner parts of the galaxies. But according to the laws of gravity, objects on the outskirts should be moving slower. The explanation: A form of matter called dark matter that does not directly interact with light. The researchers are working on another paper using a deeper survey of more than 100 million galaxies called the Dark Energy Survey.

Researchers finally set to test Einstein’s concept of the Cosmological Constant: Groundbreaking gravitational wave experiment could help us understand the expansion of the universe

February 14, 2017 12:00 am

If gravitational waves – space-time ripples traveling through the universe – are found to travel at the speed of light, there would be no need for alternative gravity theories, they say. This means dark energy would also be ruled out as an explanation, thus supporting Einstein's theory. But, if the speed of the gravitational waves is different from that of light, Einstein's theory must be revised, they say. WHAT IS DARK ENERGY Dark energy is a phrase used by physicists to describe a mysterious 'something' that is causing unusual things to happen in the universe. 'The universe is not only expanding, but it is expanding faster and faster as time goes by,' Dr Kathy Romer, scientist at the Dark Energy Survey told MailOnline.

Astronomers spot a possible dwarf planet on the edges of the Solar System

February 3, 2017 12:00 am

stronomers have discovered a trans-Neptunian object (TNO) – most likely a dwarf planet – at the edges of the Solar System, making it the second-most distant TNO currently known. The large international team that discovered it, whose lead author on the research paper is D W Gerdes from the University of Michigan, USA, found DeeDee using data from the Dark Energy Survey (DES), with followup measurements by the Atacama Large Millimetre/Submillimetre Array (ALMA). The Dark Energy Survey is an optical survey of 5000 square degrees of the southern sky and despite being used primarily for cosmological purposes, its broad off-ecliptic coverage means it is very well-suited to spotting objects within the scattered disk and other high-inclination TNO populations from the inner Oort cloud.

Computer Science Technique Helps Astronomers Explore the Universe

January 13, 2017 12:00 am

The newest telescopes, such as the Dark Energy Survey, which uses a 4-meter telescope in northern Chile and covers about one quarter of the southern sky, take millions of images of a variety of celestial objects. These often include visual distortions, cosmic rays and satellite trails that make them difficult to interpret. Deep learning could help process this deluge of data quickly. “Astronomy is the next frontier to take it on,” said Brian Nord, an astrophysicist at Fermilab in Batavia, Illinois. Nord is one of a group of astrophysicists who search for rare gravitational lenses with signs of curved slivers of light or duplicated images that indicate the presence of massive objects skewing light rays. The scientists often have to sift through numerous images by eye, one at a time. But now they have a potentially game-changing technique at their disposal.
