Astronomers using the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) instruments are unveiling new scientific research that probes some of the most extreme environments in the universe. This news will be shared in press conferences at the 248th American Astronomical Society (AAS) meeting in Pasadena, June 14th-18th.

Cosmic Dawn Fuel Discovery Unlocks Early Galaxy Growth Secrets
Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy.
Milky Way’s Black Hole Finally Caught ‘Breathing’
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have finally found clear evidence that the supermassive black hole at the center of the Milky Way, Sagittarius A*(Sgr A*), is blowing a hot cosmic wind – something scientists have been hunting for over 50 years.

Astronomers discover possible millisecond pulsar, challenging ideas about how many neutron stars lurk around the Milky Way’s central black hole
Astronomers from Breakthrough Listen have used the U.S. National Science Foundation National Radio Astronomy Observatory’s Green Bank Telescope (NSF GBT) to carry out one of the most sensitive pulsar searches ever aimed at the Milky Way’s Galactic Center.
The Galactic Center, home to the supermassive black hole Sagittarius A* and dense stellar populations, presents unique scientific opportunities and challenges for understanding stellar dynamics, extreme astrophysical environments, and tests of Einstein’s theory of General Relativity. In this research, recent Columbia University PhD graduate Karen Perez and collaborators conducted more than 20 hours of observations with the NSF GBT using the Breakthrough Listen Digital Backend, which enabled high-time and high-frequency resolution data products across a wide radio bandwidth. Of these observations, 11 hours were dedicated to the innermost 1.4 arcminutes of the Galactic Center, resulting in one of the deepest and most sensitive pulsar surveys ever performed toward this region.
These observations uncovered a promising candidate for a millisecond pulsar, with a rotation period of 8.19 milliseconds. If confirmed it would be the first such object found in the Galactic Center.
