A new study in published in Physical Review Letters analyzes the most complete set of galaxy clustering data to test the ΛCDM model, revealing discrepancies in the formation of cosmic structures ...

After the Big Bang, the universe was hot, dense, and nearly homogeneous. As the universe expanded, the material cooled, condensing after ~400,000 years into neutral atoms, freeing the cosmic microwave ...

Observations with the South Pole Telescope have revealed an independent addition to the biggest problem in cosmology.

Further evidence for the Big Bang comes from the discovery of cosmic microwave background radiation (CMBR). Astronomers discovered cosmic microwave background radiation in the 1960s. The ...

In 1927 Georges Lemaître proposed that the Universe began with an explosion called the Big Bang. Hubble’s research into the red shift of galaxy light showed that the Universe was expanding, and ...

Cosmic microwave background is a sea of radiation that provides us with evidence for the big bang. When around 1916 Einstein first used general relativity to build a cosmic model, he followed the ...

Today, searches for cosmic strings continue through gravitational wave observatories like LIGO and Virgo, as well as through ...

Researchers from IISc and RRI have developed a cutting-edge 'fantail' antenna aimed at detecting the elusive Cosmological ...

Professor Halverson works in experimental cosmology, including observations of the Cosmic Microwave Background (CMB) and mm-wave instrumentation development efforts. His previous experience at Caltech ...

The research team was combing through data of the cosmic microwave background when they discovered this apparent glitch. The ...
