Credit: West Virginia University In data gathered and analyzed over 13 years, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center (PFC) has found an intriguing low-frequency signal that may be attributable to gravitational waves. NANOGrav researchers - including a number from West Virginia University s (WVU s) Department of Physics and Astronomy and the Center for Gravitational Waves and Cosmology - measure the times of arrival of radio pulses from exotic stars called pulsars with large radio telescopes, including the Green Bank Telescope (GBT) in Pocahontas County, West Virginia. Pulsars are small, dense stars that rapidly rotate, emitting beamed radio waves, much like a lighthouse. The results from this most recent dataset show perturbations in the arrival times from these pulsars that may indicate the effects of gravitational waves, as reported recently in ....
Next Generation VLA Endorsed by Canadian Panel Credit: Sophia Dagnello, NRAO/AUI/NSF The Canadian Astronomy Long Range Plan 2020-2030, a report on priorities and recommendations for Canadian astronomy over the next decade, has recommended that Canada support the National Radio Astronomy Observatory’s (NRAO) proposed Next Generation Very Large Array (ngVLA), saying the new facility will enable transformational science across many areas of astrophysics. The ngVLA will be an array of 263 dish antennas reaching across North America. Both its sensitivity to faint objects and its resolving power ability to see fine detail will be 10 times greater than the current VLA. Building on the scientific and technical legacies of the VLA and the Atacama Large Millimeter/submillimeter Array (ALMA), the ngVLA is being designed to provide the next major leap forward in our understanding of planets, galaxies, black holes, and the dynamic sky. The ngVLA’s capabilities will compleme ....

Successful Test Paves Way for New Planetary Radar Credit: NRAO/GBO/Raytheon/NSF/AUI The National Science Foundationâs Green Bank Observatory (GBO) and National Radio Astronomy Observatory (NRAO), and Raytheon Intelligence & Space conducted a test in November to prove that a new radio telescope system can capture high-resolution images in near-Earth space. GBO’s Green Bank Telescope (GBT) in West Virginia â the world’s largest fully steerable radio telescope â was outfitted with a new transmitter developed by Raytheon Intelligence & Space, allowing it to transmit a radar signal into space. The NRAO’s continent-wide Very Long Baseline Array (VLBA) received the reflected signal and produced images of the Apollo 15 moon landing site. ....
