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.
ALMA Spots Monstrous Baby Galaxies Cradled in Dark Matter
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a nest of monstrous baby galaxies 11.5 billion light-years away. These young galaxies seem to reside at the junction of gigantic filaments in a web of dark matter. These findings are important for understanding how monstrous galaxies like these form and how they evolve into huge elliptical galaxies.
A press release on these results was issued by The University of Tokyo in Japanese. The English version was translated by the National Astronomical Observatory of Japan. The full text is available here.

This observation result was published as Umehata et al. “ALMA Deep Field in SSA22: A concentration of dusty starbursts in a z=3.09 protocluster core” in theAstrophysical Journal Letters, issued on December 4, 2015.
The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of the European Organisation for Astronomical Research in the Southern Hemisphere (ESO), the U.S. National Science Foundation (NSF) and the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Republic of Chile. ALMA is funded by ESO on behalf of its Member States, by NSF in cooperation with the National Research Council of Canada (NRC) and the National Science Council of Taiwan (NSC) and by NINS in cooperation with the Academia Sinica (AS) in Taiwan and the Korea Astronomy and Space Science Institute (KASI).
ALMA construction and operations are led by ESO on behalf of its Member States; by the National Radio Astronomy Observatory (NRAO), managed by Associated Universities, Inc. (AUI), on behalf of North America; and by the National Astronomical Observatory of Japan (NAOJ) on behalf of East Asia. The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.
