As they reported in a study in Physical Review Letters, researchers from the University of Manchester searched for hints by comparing the distribution of galaxies to the cosmic microwave ...

Recent constraints on anisotropic cosmic birefringence enhance our understanding of CMB polarization and its implications for ...

The Cosmic Microwave Background carries with it a record of events throughout the 13.8-billion-year history of the universe.

As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang.

Specifically, the Lambda CDM explains observations of the cosmic microwave background, which is the afterglow of microwave radiation from when the universe was in a “hot, dense state ” about ...

The cosmic microwave background offered a new window into the nature of reality, one into which astronomers have been peering intently ever since.

Previously, the gold standard for cosmic microwave background measurements was the data from the Planck satellite, taken more than a decade ago. Now the new South Pole Telescope data, when combined ...

The photos show light, dark and the polarization of light—background radiation known as the cosmic microwave background, and details the movement of hydrogen and helium gas at the beginning of ...

Scientists are using secondary signatures from the cosmic microwave background to map the universe’s hidden matter.
