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 ...

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 ...

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 ...

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 ...
