MeerKAT directly detects faint hydrogen signal from the distant universe
Astronomers from the University of Manchester and the University of the Western Cape have directly detected an extremely faint radio signal from hydrogen gas billions of light-years away, opening a powerful new way to map the large-scale structure of the universe. Using South Africa's MeerKAT radio telescope, the international team measured radio emissions from neutral hydrogen dating back to a time when the universe was several billion years younger than it is today.
An extremely weak radio signal of neutral hydrogen can be detected directly in MeerKAT data over billions of light-years. Astronomers have measured the common 21-centimeter radiation of many unresolved galaxies without combining the radio data with an optical galaxy mapping. The success strengthens a method that in future could efficiently capture large parts of the cosmic matter distribution. Cape Town (South Africa). Neutral [...] Die Beitrag …
