Massive Gas Reservoir Discovered in Early Universe Galaxy
Astronomers have detected cold molecular gas in REBELS-25, a massive star-forming galaxy observed just a few hundred million years after the Big Bang. Using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Very Large Array (VLA), researchers identified a massive gas reservoir, marking the highest-redshift detection of a low-J CO transition to date. This discovery … Read more
