After a complex statistical analysis of some one million galaxies, a team of researchers at several Chinese universities, and the University of Cordoba was able to publish the results of the study in ...

Distance indicators such as standard candles and standard rulers provide a direct route to mapping the expansion history of the Universe. By comparing observed fluxes or angular sizes of astrophysical ...

Despite a century of measurements, astronomers can’t agree on the rate at which the universe is expanding. A technique that relies on measuring distances to a specific type of aging star in other ...

The SuperNova Legacy Survey is an international collaboration involving about 40 researchers, that aims to discover several hundred far supernovae and mesure their distance. The team's first results ...

Measuring cosmological distances is tricky at the best of times, but it is even harder if your ruler isn’t up to scratch. A new cosmological standard ruler could make the difference – and help ...

A team of researchers from the collaboration Sloan Digital Sky Survey III (SDSS-III) have presented this week the latest results obtained from the map obtained by the consortium with data collected ...

Cosmological models with varying fundamental constants explore the possibility that quantities traditionally regarded as immutable—such as the speed of light (c), Newton’s gravitational constant (G) ...
