2024年1月9日 · Astronomers using NASA's Hubble Space Telescope have found a rare event in an oddball place. It's called a fast radio burst (FRB), a fleeting blast of energy that can – for a few milliseconds – outshine an entire galaxy. Hundreds of FRBs have been detected over the …

Fast radio bursts are bright, unresolved (pointsource-like), broadband (spanning a large range of radio frequencies), millisecond flashes found in parts of the sky. Unlike many radio sources, the signal from a burst is detected in a short period of time with enough strength to …

2019年9月13日 · This handbook provides recommended guidelines for creating and conducting failure review boards (FRBs) and anomaly review boards (ARBs).

2021年5月20日 · Astronomers using NASA's Hubble Space Telescope have traced the locations of five brief, powerful radio blasts to the spiral arms of five distant galaxies. Called fast radio bursts (FRBs), these extraordinary events generate as much energy in a thousandth of a second as the Sun does in a year.

2024年1月9日 · A Hubble Space Telescope image of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble's sensitivity and sharpness reveals a compact group of multiple galaxies that may be in the process of merging.

2021年5月20日 · Fast radio bursts or FRBs, are extraordinary events that generate as much energy in a thousandth of a second as the Sun does in an entire year! Astronomers, using NASA’s Hubble Space Telescope have traced the locations of eight brief, powerful FRBs; five of which are near or on their host galaxy’s spiral arms.

2025年3月14日 · Following the detection of the binary compact object merger event S250206dm by the LIGO-Virgo-KAGRA Collaboration (GCN 39175), the CHIME/FRB collaboration reported a fast radio burst, FRB 20250206A (GCN 39216). The burst occurred less than one minute after S250206dm, with an estimated spatial coincidence probability of 0.1%.

2025年2月7日 · The FRB was detected with a signal-to-noise ratio of 16.4 in one CHIME/FRB beam, and 15.7 in a second beam. A preliminary baseband fluence averaged over the entire 400-800 MHz CHIME observing band is 36 +/- 4 Jy ms (1-sigma uncertainty).

2020年11月4日 · The flare-up included the first fast radio burst (FRB) ever seen from within our Milky Way galaxy and shows that magnetars can produce these mysterious and powerful radio blasts previously only seen in other galaxies.
