Green Bank hosts new telescope for CHIME

CHIME Outrigger telescopes boost search for fast radio bursts

CHIME’s new siblings will pinpoint bursts detected by Canada’s world-renowned telescope

In the quest to identify the origins of one of astronomy’s biggest mysteries – fast radio bursts (FRBs) – Canada’s world-renowned telescope, the Canadian Hydrogen Intensity Mapping Experiment (CHIME), is getting backup.

Scientists using the National Science Foundation’s Green Bank Telescope (GBT) and China’s Five-hundred-meter Aperture Spherical radio Telescope (FAST) have teamed up to shed light on the origin of the thousands of mysterious fast radio bursts that hit the Earth each day from locations far beyond the Milky Way.

In partnership with National Radio Astronomy Observatory (NRAO) and Raytheon Intelligence &
Space (RI&S), the Green Bank Observatory (GBO) tested a multi-static radar intended to expand
the scientific reach and capability of the Green Bank Telescope (GBT) and the Very Long Baseline
Array (VLBA).


Are astronomers seeing a signal from giant black holes?

World-wide radio telescope network strengthens evidence for signal that may hint at ultra-low frequency gravitational waves

Artist’s impression of the IPTA experiment — an array of pulsars around the Earth embedded in a gravitational wave background from supermassive black hole binaries. The signals from the pulsars measured with a network of global radio telescopes are affected by the gravitational waves and allow for the study of the origin of the background.

An international team of astronomers has discovered what could be the early sign of a background signal arising from supermassive black holes, observed through low-frequency gravitational waves. These scientists are comparing data collected from several instruments, including the National Science Foundation’s Green Bank Telescope (GBT.)
