Using the world’s largest, fully steerable radio telescope — the National Science Foundation’s Robert C. Byrd Green Bank Telescope (GBT) in W.Va. — an international team of researchers has given ...

Scientists are championing a relatively new technique as a method to understand the structure of the early universe in three dimensions. With enough time and magnifying power, a telescope can gather ...

The intensity mapping of neutral hydrogen employs measurement of the unresolved 21 cm emission across wide areas of the sky to trace the large-scale distribution of matter. Rather than detecting ...

Add Yahoo as a preferred source to see more of our stories on Google. A section of the line-intensity map created using HETDEX data, showing a swath of the universe as it appeared 10 billion years ago ...

Line intensity mapping (LIM) is an observational technique that measures the integrated emission of spectral lines across large cosmological volumes without resolving individual sources. By capturing ...

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...
