7,000 Galaxy Clusters, Hiding in Plain Sight
Physicists have identified over 7,000 galaxy clusters using data from the South Pole Telescope. By analyzing distortions in the cosmic microwave background, researchers can better understand dark matter and the evolution of the universe.
Why it matters
This catalogue provides a critical dataset for testing fundamental cosmological theories regarding dark matter and dark energy.
How do you weigh something you cannot see, hiding in light that is nearly as old as the universe itself? A team led by physicists at Argonne National Laboratory has just published an answer, in the form of a catalogue containing more than seven thousand galaxy clusters, built from five years of observations by the South Pole Telescope.
