Astronomers use ALMA to observe distant starburst galaxies, detecting water in one for the first time. The team finds that these galaxies formed stars at a furious pace 12 billion years ago, earlier than previously thought.
A team of astronomers has found galaxies producing stars at a prodigious rate when the universe was just a billion years old. The discovery, enabled by the Atacama Large Millimeter Array (ALMA), provides valuable data for refining theoretical models of star and galaxy formation in the early universe.
A team of astronomers has captured stunning images of a nearby dwarf galaxy undergoing a 'stealth merger' with its host. The resulting stellar stream is visible in the outer regions of NGC 4449, providing insights into galaxy formation and evolution.
Astronomers using ALMA have found compelling evidence for how star-forming galaxies evolve into 'red and dead' elliptical galaxies, catching a large group of galaxies right in the middle of this change. The study reveals that galaxies are being starved of star-forming gas by their central black holes' jets.
Researchers found that ultraviolet radiation from massive stars evaporated gas in intergalactic medium, clearing a narrow cone-shaped passage. This process helps explain why similar phenomena in other galaxies were difficult to detect.
Astronomers find that galaxies in this 'sweet spot' mass range can form stars at high rates and grow rapidly.
