The National Science Foundation (NSF) has awarded an additional $4M to the National Radio Astronomy Observatory (NRAO) and Associated Universities, Inc. (AUI) to fund the design and development of the next generation Very Large Array (ngVLA). With this funding increment, NSF has created a cooperative support agreement for this new planned radio...
Astronomers using National Science Foundation (NSF) radio telescopes have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers of pairs of neutron stars into a “cosmic ruler” capable of measuring the expansion of the Universe and resolving an outstanding question over...
Astronomers using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) have discovered a fast-moving jet of material propelled outward from a type of neutron star previously thought incapable of launching such a jet. The discovery, the scientists said, requires them to fundamentally revise their ideas about how such jets...
Precise measurement using a continent-wide collection of National Science Foundation (NSF) radio telescopes has revealed that a narrow jet of particles moving at nearly the speed of light broke out into interstellar space after a pair of neutron stars merged in a galaxy 130 million light-years from Earth. The merger, which occurred in August of...
