NSF NRAO Radio Telescopes Help Reveal Cloud-9, a Starless Dark-Matter “Failed Galaxy” Near M94
Astronomers using a powerful combination of radio and optical telescopes have confirmed that a peculiar gas cloud near the spiral galaxy M94 is a “failed” galaxy; a dark-matter-dominated halo filled with gas but entirely lacking stars.
Hidden Giants of the Early Universe: NSF NRAO Telescopes Help Reveal Divergent Fates of the Most Massive Galaxies
Astronomers using the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) instruments Atacama Large Millimeter/submillimeter Array (ALMA) and, the U.S. National Science Foundation Very Large Array (NSF VLA), and the W. M. Keck Observatory have uncovered the hidden lives of some of the most massive galaxies in the early Universe, revealing that while some shut down star formation quickly, others continue forming stars behind thick veils of cosmic dust.
Radio Black Hole Trio Lights Up in Rare Galaxy Merger
Astronomers from the U.S. Naval Research Laboratory (NRL), in conjunction with scientists from the U.S. Naval Observatory (USNO) and NASA Goddard Space Flight Center (NASA GSFC), using U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) instruments have confirmed the first known triple system in which all three galaxies host actively feeding, radio-bright supermassive black holes.
