A new study, published on Arxiv, has deepened the cosmic puzzle surrounding the “Hubble tension,” an ongoing debate about the universe’s expansion rate. The findings come from the Atacama Cosmology ...

Cosmologists are preparing to cast their sharpest-ever eyes on the early Universe. From an altitude of 5,300 metres on Cerro Toco, in northern Chile’s Atacama Desert, the Simons Observatory will map ...

Light is defined as "polarized" when its electromagnetic field oscillation exhibits a preferred orientation, a phenomenon observable in various contexts, including the blue sky. The Cosmic Microwave ...

"It means cleaning house, narrowing the viable paths forward, and no longer spending energy on what are evidently dead ends." When you purchase through links on our site, we may earn an affiliate ...

The South Pole Telescope has seen B-mode polarization in the CMB. (Courtesy: Stephen Hoover/University of Chicago) The South Pole Telescope (SPT) has made the first detection of a subtle twist in ...

Infrared cosmos: the cosmic infrared background at 857 GHz as seen by the European Space Agency's Planck mission. (Courtesy: ESA/Planck) Physicists in the UK and the US have shown how to use one kind ...

– Neutrinos: Neff or “dark radiation” requires de-lensed polarization spectra; ∑mν requires CMB-lensing (and τe). – Dark Energy: CMB-lensing correlations with galaxy surveys; CMB-lensing cluster ...

Gravitational waves from inflation generate a faint but distinctive twisting pattern in the polarization of the cosmic microwave background, known as a "curl" or B-mode pattern. For the density ...

With the end of Europe’s major Planck mission, researchers are moving to smaller projects studying different aspects of the cosmic microwave background. A transformative era in cosmological science ...

It may be curtains for the Atacama Cosmology Telescope (ACT), but the final data from its nearly 20 years of observations have laid out a roadmap for the future investigation of the cosmos. The data, ...

A transformative era in cosmological science ended this week when the European Space Agency’s Planck telescope released its final maps of the early Universe. Planck was the last in a line of three ...
