ALMA Observes More Than Ever Before

New Discovery Challenges Evolution of Galaxy Clusters

Peering back in time, around 12 billion years, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found the most distant and direct evidence of scorching gas in a forming galaxy cluster, SPT2349-56. The hot plasma, seen when the Universe was just 1.4 billion years old, is far hotter and more pressurized than current theories predicted for such an early system.

Cosmic Lens Reveals Hyperactive Cradle of Future Galaxy Cluster

Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a rare protocluster that was exceptionally bright, all when the Universe was 11 billion years younger. The system, called PJ0846+15 (J0846), is the first strongly lensed protocluster core discovered, revealing how some of the most massive galaxy clusters in the present-day Universe began their lives.

Stars That Die Off the Beaten Path

Astronomers have created a detailed forecast of where they expect to observe future stellar explosions in a nearby galaxy, opening a new window into how exploding stars shape the cosmos.

The Atacama Large Millimeter/submillimeter Array (ALMA) is thrilled to announce that a record-breaking total of 4,250 hours of science-quality data were successfully collected on the 12-m Array during Cycle 10. This surpasses the previous record of 3,787 hours achieved during Cycle 5, reflecting a significant enhancement in observational efficiency and scientific output. ALMA also set new records on its other arrays, with 3,769 hours recorded on the 7-m Array and 2,723 hours on the Total Power Array. 

“This accomplishment is a direct result of the exceptional teamwork and dedication of everyone involved in the ALMA collaboration,” commented Sergio Martin, ALMA Head of the Department of Science Operations. “Achieving this level of scientific output reflects the improved operational efficiency that allows us to better cope with the growing demand for ALMA’s cutting-edge capabilitiesWe are excited to see the scientific discoveries emerging from the unprecedented amount of data that ALMA collects.” 

This remarkable achievement is a testament to ALMA’s global team’s hard work, coordination, and dedication, including the Joint ALMA Observatory and the partner regions in East AsiaEurope, and North America. The steady increase in observing hours across recent cycles showcases ALMA’s ongoing commitment to pushing the boundaries of astronomical discovery.
