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 ...

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 ...

Several major metropolitan areas are in considerable danger of disastrous “earthquake shaking” from upcoming geological ...

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the largest, most accurate 3D map yet of the light emitted by excited hydrogen in ...

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 ...

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 ...

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 ...
