International Team Observes First Radio Counterpart to Gravitational Waves

WASHINGTON – Radio astronomers at the U.S. Naval Research Laboratory (NRL), Radio Astrophysics and Sensing Section, in collaboration with an international team from the Caltech-led Global Relay of Observatories Watching Transients Happen (GROWTH) project, measured the first ever detection of radio emission from colliding neutron stars nearly 124 million light years from Earth. The team discovered radio frequency emission in the range of 3 and 6 GHz in data taken Sept. 2 -3, 2017. More

NRL Brightens Perspective of Mysterious Mini-Halos

(WASHINGTON• August 3, 2017) -The largest gravitationally bound objects in the universe are galaxy clusters that form at the intersection of cosmic web filaments. These entities are shaped and grow through massive collisions as material streams into their gravitational pull. Within the heart of some galaxy clusters are mysterious and little known radio mini-halos. These rare, dispersed, and steep-spectrum (brighter at low frequencies) radio sources surround a bright central radio galaxy and are highly luminous at radio wavelengths. More

NRL Astronomers Inspire Youth to Gaze at Stars

NRL Experiments Transition Flawlessly Aboard ISS

The International Space Station (ISS) installed NRL’s Limb-Imaging Ionospheric and Thermospheric Extreme Ultraviolet (UV) Spectrograph (LITES), and Global Positioning System (GPS) Radio Occultation and Ultraviolet Photometer Co-located (GROUP-C) research instruments Feb 28.

The payload was delivered via SpaceX’s FALCON 9 rocket Feb. 17, and later retrieved by a robotic-arm aboard the ISS. After several days of installation, payload managers and the DoD Space Test Program successfully performed tests to confirm the instruments functioned properly. More
