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 ...
The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, hydrogen-blue glow that had mostly escaped surveys until now. Astronomers working ...

A new Caltech instrument called TIME just began mapping ancient galaxies by tracking a single spectral line across cosmic distances
Somewhere in the millimeter-wave static that washes over southern Arizona, there is a faint signal from galaxies that lit up ...
Astronomers have produced one of the most accurate, comprehensive cosmic maps ever made, revealing a brilliant "sea of light" that permeated the early universe. Unlike other universal maps, this 3D ...
