From The Mac Observer, Nov. 25, 2019: In this 30-minute podcast episode, Fermilab scientist Dan Hooper recounts how he caught the astrophysics bug as an undergraduate, landed a postdoc position at Oxford and was later hired at Fermilab. He chats about his interest in the interface between particle physics and cosmology, dark matter and what neutrinos can tell us about the early universe.

From Science, Nov. 12, 2019: Three years ago, a team of particle astrophysicists appeared to nix the idea that a faint glow of gamma rays in the heart of our Milky Way galaxy could be emanating from dark matter. But the conclusion that the gamma rays come instead from more ordinary sources may have been too hasty, the team reports in a new study. So the dark matter hypothesis may be alive and well after all. Fermilab scientist Dan Hooper is quoted in this article.

From Gizmodo, Nov. 6, 2019: Scientists analyzing data from a defunct satellite say we should all consider that our universe might be round, rather than flat. The consequences, they explain in a new paper, could be crisis-inducing. Fermilab scientist Dan Hooper weighs in on this tension in cosmology.

When the Large Synoptic Survey Telescope high in the Chilean Andes becomes fully operational in 2022, its 3.2-gigapixel camera will collect the same amount of data — every night. And it will do so over and over again for ten years. The sky survey will collect so much data that data scientists needed to figure out new ways for astronomers to access it.

From In the Moment, Oct. 31, 2019: In this 42-minute podcast, Fermilab scientist Dan Hooper talks about particles, relativity and the origins of our universe, outlining our growing understanding of the conditions in which our universe began, highlighting what we know about the first few seconds after the Big Bang and how several astronomers and mathematicians throughout history helped us determine that the universe was expanding.

From Descoperă.ro, Oct. 31, 2019: Deep Underground Neutrino Experiment a fost conceput pentru a înţelege mai bine neutrino şi degradarea protonilor. Într-un studiu recent, o echipă de cercetători de la Universitatea Ohio explică faptul că DUNE ar putea să îi ajute pe cercetători să realizeze o serie de descoperiri fundamentale legate de neutrinii solari, notează Phys.

Berkeley Lab’s Dark Energy Spectroscopic Instrument aimed its robotic array of 5,000 fiber-optic “eyes” at the night sky Oct. 22 to capture the first images showing its unique view of galaxy light. It was the first test DESI with its nearly complete complement of components. Fermilab contributed key elements to DESI, including the corrector barrel, hexapod, cage and CCDs. Fermilab also provided the online databases used for data acquisition and the software for the instrument’s robotic positioners.

From UChicago News, Oct. 18, 2019: The Department of Energy has honored University of Chicago scientists Josh Frieman, also of Fermilab, and Ian Foster, also of Argonne National Laboratory, for their transformative research and scientific leadership, selecting them as part of its inaugural Office of Science Distinguished Scientist Fellowship program. Frieman was listed for “pioneering advances in the science of dark energy and cosmic acceleration, including leading the Sloan Digital Sky Survey-II Supernova Survey, co-founding the Dark Energy Survey and service as its director.”
