From Inside Science, Jan. 24, 2020: Some scientists have been poking at the foundations of dark energy, but many say the concept remains on solid, if mysterious, ground. Fermilab scientist Josh Frieman is quoted in this story on the evidence for dark energy.
The first undergraduate on the Event Horizon Telescope to receive junior collaborator status thrives in the unknown. In his nearly two years with the team, he has developed computer libraries for data analysis and modeling, made movies of black holes and assisted with weather prediction.
From SLAC, Jan. 13, 2020: Matching up maps of matter and light from the Dark Energy Survey, hosted at Fermilab, and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint cosmic gamma-ray glow.
For the first time, a team of scientists has used the orientation of light left over from the early universe to detect gravitational lensing from galaxy clusters – the bending of light around these massive objects. Using gravitational lensing data taken by the South Pole Telescope and the Dark Energy Camera, Fermilab scientist Brad Benson and colleagues have demonstrated a new way to “weigh” galaxy clusters and ultimately shed light on dark matter, dark energy and other mysteries of the cosmos.
From CNN, Jan. 1, 2020: Fermilab scientist Don Lincoln discusses how Betelgeuse, a star in the constellation Orion and one of the brightest stars in the heavens, has observably dimmed in recent months, a sign that some astronomers interpret as a warning that the star will explode in one of the most powerful and dramatic events in all of the cosmos — a supernova.
From Gizmodo, Dec. 13, 2019: Fermilab scientist Dan Hooper is quoted in this article on a new paper that says dark matter could be responsible for the mysterious observation of gamma rays in the center of our galaxy.
The Large Synoptic Survey Telescope, a flagship astronomy and astrophysics project currently under construction on a mountaintop in Chile, will be named for astronomer Vera Rubin, a key figure in the history of the search for dark matter.
From New Scientist, Dec. 11, 2019: Fermilab scientist Dan Hooper is quoted in this article on what scientists mean when they talk about the Big Bang. The best evidence for the big bang is all around us in the cosmic microwave background, the radiation released once the universe had cooled sufficiently for atoms to form, when it was about 380,000 years old. And that is the point: everywhere in today’s universe was where the big bang was.
Scientists at CERN have found a way to learn more about the interior of neutron stars using the Large Hadron Collider. Researchers on the ALICE experiment are uncovering the properties of elusive hyperon particles hypothesized to be found inside neutron stars.
