Astronomers find massive gas reservoir in early galaxy
Tech Explorist··17 Jun
Tech Explorist reported that astronomers discovered a massive cold molecular gas reservoir in REBELS-25, a star-forming galaxy that existed only a few hundred million years after the Big Bang.

What It Means For You
- The discovery helps explain how early galaxies formed stars so quickly.
- Cold molecular gas is the fuel from which stars are born.
- Next-generation telescopes may map similar gas reservoirs across the early universe.
What's Happening
- Researchers studied REBELS-25 at redshift 7.31.
- They used VLA, ALMA and radiative transfer modelling.
- The work was published in Monthly Notices of the Royal Astronomical Society.
Science Context
- The epoch of reionization occurred in the universe's first billion years.
- CO and CII emissions can trace molecular gas at high redshift.
- The team used TUNER to model gas and dust emission under high cosmic microwave background conditions.
