ALMA Scientists Find Pair of Black Holes Dining Together in Nearby Galaxy Merger
ALMA Scientists Find Pair of Black Holes Dining Together in Nearby Galaxy Merger
January 9, 2023 at 12:15 pm | News Release

While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA)— an international observatory co-operated by the U.S. National Science Foundation’s National Radio Astronomy Observatory (NRAO)— scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What’s more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe. The results of the new research were published today in The Astrophysical Journal Letters, and presented in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.

Hydrogen Masers Reveal New Secrets of a Massive Star to ALMA Scientists

While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star’s gas disk at impossibly high speeds. What’s more, they believe the jet is caused by strong magnetic forces surrounding the star. The discovery could help researchers to understand the nature and evolution of massive stars and how hydrogen masers are formed in space. The new observations were presented today in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.

ALMA and JWST Reveal Galactic Shock is Shaping Stephan’s Quintet in Mysterious Ways
ALMA and JWST Reveal Galactic Shock is Shaping Stephan’s Quintet in Mysterious Ways
January 9, 2023 at 1:15 pm | News Release

Shockwaves resulting from the violent collision between an intruder galaxy and Stephan’s Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST) have revealed that a sonic boom several times the size of the Milky Way has kickstarted a recycling plant for warm and cold molecular hydrogen gas. What’s more, scientists uncovered the break-up of a giant cloud into a fog of warm gas, the possible collision of two clouds forming a splash of warm gas around them, and the formation of a new galaxy. The observations were presented today in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.

ALMA Has Successfully Restarted Observations
December 19, 2022 at 10:01 am | Announcement

Forty-eight days after suspending observations due to a cyberattack, the Atacama Large Millimeter/submillimeter Array (ALMA) is observing the sky again. The computing staff has worked diligently to rebuild the affected JAO computer system servers and services. This is a crucial milestone in the recovery process.
