cosmology

NPR’s Short Wave host spoke with Fermilab Cosmologist Brian Nord about what dark energy could be and what it implies about the end of our universe.

Fermilab Cosmologist Alex Drlica-Wagner explains recent research charge-coupled devices placed on the SOAR telescope in Chile called Skipper CCDs. Skipper CCDs hold immense potential beyond observing the cosmos including medical imaging and radioisotope detection.

Enabled by a U.S. Department of Energy program, a collaboration of scientists from Fermilab, UChicago, NOIRLab and other institutions demonstrated that skipper-CCD detectors can be utilized to improve cosmology research

How are cosmology and particle physics connected? Observing the motions of stars and galaxies can reveal the influence of as-yet-undiscovered particles, while studying fundamental particles in the lab can tell us about the birth and evolution of the cosmos.

The most recent results from Dark Energy Survey of over 1,500 supernovas taken by the by the DECam calls the standard model of cosmology into question.

To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB.

Just because matter is visible doesn’t mean it’s easy to see.

From Physics, Jan. 31, 2023: Fermilab scientists are part of a group of researchers using cross-correlation measurements combining data from the Dark Energy Survey and the South Pole Telescope to determine cosmological parameters with greater precision. The analysis involved more than 150 researchers with results published as a set of three articles in Physical Review D.

Their analysis combines Dark Energy Survey, South Pole Telescope data to better understand the evolution of universe.

From Big Think, Nov. 2, 2022: Don Lincoln explores Hubble tension, two very precise yet conflicting estimates of the rate at which the Universe is expanding. While the of Universe expansion is consistent, the two ways in which this is measured begs the question if something is missing in cosmology theory.
