ALMA Discovers Massive Rotating Disk in Early Universe
National Radio Astronomy Observatory

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk galaxy, seen when the universe was only ten percent of its current age, challenges the traditional models of galaxy formation. This research appears on 20 May 2020 in the journal Nature.

NRAO’s Central Development Laboratory: Making the Invisible Visible
National Radio Astronomy Observatory

Nestled among the hills of the University of Virginia campus are a couple of nondescript buildings. They are home to NRAO’s Central Development Laboratory (CDL). The buildings are easy to overlook, just as it is easy to overlook the work done by CDL. We see photographs of the radio dishes at Atacama Large Millimeter/submillimeter Array (ALMA) and the Very Large Array (VLA) under a starry sky, and the beautifully rendered scientific images they produce. But between these two extremes is a complex set of processes that transform the faint radio signals of distant space into usable scientific data. Achieving that transformation effectively is one of CDLs most important jobs.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.
