New Receivers Achieve First Light, Set Record for Observational Capabilities at ALMA
September 7, 2021 at 5:05 pm | News Release

A new set of receivers installed on antennas at the Atacama Large Millimeter/submillimeter Array (ALMA) have achieved first light. With it, they set a new record for the longest wavelengths visible with the radio array. The achievement has opened a window on the Universe previously inaccessible at the telescope, thanks to an international team of engineers, including engineers from the National Radio Astronomy Observatory (NRAO).

A new study from scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) suggests that previously displaced gases can re-accrete onto galaxies, potentially slowing down the process of galaxy death caused by ram pressure stripping, and creating unique structures more resistant to its effects.
