NRAO is supporting a Mexican astronomer’s work to select and develop antenna sites in northern Mexico for the Next Generation Very Large Array (ngVLA).
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA)— an international observatory co-operated by the US National Science Foundation’s National Radio Astronomy Observatory (NRAO)— have for the first time recorded millimeter-wavelength light from a fiery explosion caused by the merger of a neutron star with another star. The team also confirmed this flash of light to be one of the most energetic short-duration gamma-ray bursts ever observed, leaving behind one of the most luminous afterglows on record.
A team of engineers testing the design efficiency of reflectors for the National Radio Astronomy Observatory’s upcoming next generation Very Large Array (ngVLA) has received the Institute of Electrical and Electronics Engineers (IEEE) Harold A. Wheeler Applications Prize Paper Award.
Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes.
The Planetary Science Decadal Survey indicated that new ground-based radar systems will be vital research tools for planetary defense and studying planets, moons, asteroids, and other Solar System objects. The National Radio Astronomy Observatory and the Green Bank Observatory are developing new capabilities for the Green Bank Telescope and the Very Long Baseline Array that will meet those needs.
Recent advancements in 3D printing (also known as additive manufacturing) for metallic structures make it possible to print all-metal electromagnetic devices—like antennas and waveguides—on demand. A new partnership between the National Radio Astronomy Observatory, headquartered in Charlottesville, Virginia, and Optisys, LLC, headquartered in West Valley City, Utah, will explore the potential for leveraging this technology for radio astronomy applications.
Dr. Tony Beasley, Director of the National Radio Astronomy Observatory and AUI Vice President for Radio Astronomy Operations, was today elected as a fellow of the American Association for the Advancement of Science (AAAS).
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) made a rare detection of a likely stellar flyby event in the Z Canis Majoris (Z CMa) star system. An intruder—not bound to the system—object came in close proximity to and interacted with the environment surrounding the binary protostar, causing the formation of chaotic, stretched-out streams of dust and gas in the disk surrounding it.
Released in November 2021, the Astronomy and Astrophysics Decadal Survey—Astro2020—not only set scientific priorities for the discovery and study of potentially habitable worlds and finding answers to big questions about the nature of the Universe, but also emphasized the importance of diversity, equity, and inclusion (DEI) in the field of astrophysics. The inclusion of DEI initiatives in the report signals a shift in the industry, one for which the National Radio Astronomy Observatory (NRAO) and its partners have been building a foundation for over a decade.
The National Science Foundation (NSF) has awarded the National Radio Astronomy Observatory’s Central Development Laboratory (CDL) $250,000 in Partnerships for Innovation (PFI) funding to support the proof-of-concept development of high-performance reflectionless radio frequency filters at 40 GHz and above for high-frequency applications, including wireless and defense.
