From Quanta, Aug. 3, 2017: Fermilab scientists Josh Frieman and Scott Dodelson talk about the latest major result from the Dark Energy Survey, which could signal the start of a new era of cosmology.
From the DOE Office of Science, June 21, 2017: Dark Energy Survey Director Josh Frieman appears in this Office of Science article, which surveys research projects that will help us better understand the phenomenon that is accelerating the universe’s expansion.
Scientists furthered studies of the Higgs boson, neutrinos, dark matter, dark energy and cosmic inflation and continued the search for undiscovered particles, forces and principles.
Powerful survey instruments help us map the sky with incredible precision. But what ensures that the instruments themselves are precisely built?
A theoretical particle that adapts to its surroundings could explain the accelerating expansion of our universe.
From Berkeley Lab, Aug. 9, 2016: DESI, the Dark Energy Spectroscopic Instrument, will measure light from 35 million galaxies to provide new clues about dark energy. Fermilab is a collaborator on the Berkeley Lab project.
How do scientists know what percentages of the universe are made up of dark matter and dark energy? Cosmologist Risa Wechsler of the Kavli Institute for Particle Astrophysics and Cosmology explains. Watch the 3-minute video.
The Fermilab Art Gallery welcomes “Art of Darkness,” a new exhibit of images from the Dark Energy Survey, including dazzling pictures of the cosmos captured with the Dark Energy Camera.
Scientist Marcelle Soares-Santos talks about Brazil, neutron stars and a love of discovery.
Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discovered eight more faint celestial objects hovering near our Milky Way galaxy. Signs indicate that they, like the objects found by the same team earlier this year, are likely dwarf satellite galaxies, the smallest and closest known form of galaxies.
