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.
Fermilab’s quantum program includes a number of leading-edge research initiatives that build on the lab’s unique capabilities as the U.S. center for high-energy physics and a leader in quantum physics research. On the tour, researchers discussed quantum technologies for communication, high-energy physics experiments, algorithms and theory, and superconducting qubits hosted in superconducting radio-frequency cavities.
From Quanta, Jan. 9, 2019: Fermilab scientist Alex Drlica-Wagner comments on dark matter in this article on a paradoxical problem in astronomy: New surveys have allowed astronomers to find more satellite galaxies that had previously been hidden. At the same time, updated computer simulations predicted the existence of far fewer galaxies than their predecessors did.
From Live Science, Jan. 1, 2019: One of the four is MiniBooNE’s search for a fourth neutrino, which could be a dark matter candidate.
From Futurism, Dec. 11, 2018: No matter how confident we are that it’s out there, dark matter continues to evade our brightest physicists. Now, yet another experiment designed to pick up on signs of dark matter’s presence has turned up nothing at all. Fermilab’s Dan Hooper comments on results from the COSINE-100 experiment.
From Science News, Dec. 5, 2018: The COSINE-100 searched for particles using the same type of detector as another experiment, whose researchers said they had strong evidence that dark matter was interacting in their detector. COSINE-100 found no evidence of the evasive subatomic particles. Fermilab scientist Dan Hooper comments on COSINE-100’s findings.
From CNN, Nov. 20, 2018: Fermilab scientist Don Lincoln talks about a stellar stream called S1, which consists of nearly 100 stars of similar age and composition, orbiting the Milky Way in a direction exactly opposite that of normal stars.
