TIME instrument unlocks faint signals from early galaxies across vast stretches of sky

Phys · · 904 words · By Kate Blackwood

Cornell astronomers have developed and tested the Tomographic Ionized-carbon Mapping Experiment (TIME), an instrument that uses line-intensity mapping to observe the combined glow of early galaxies. The team validated the instrument by observing Sagittarius A at the center of the Milky Way before moving on to more distant cosmic targets.
