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.
After less than a year of data taking, DESI has already mapped out more galaxies than all previous 3D surveys combined — and it’s just getting started.
Physicists are revisiting what they previously assumed about how dark matter interacts with itself.
Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once.
