... search took an unexpected turn when astronomers discovered a new cosmological phenomenon called a fast radio burst (FRB). These highly energetic pulses of radio emission appear to come from random directions in the sky and last for just milliseconds...
... survey a million stars - most of the stars within 300 parsecs - for evidence of radio emissions in the classically identified low-noise part of the radio spectrum. The latter survey requires an array telescope with multiple, electronically pointed...
..., as in addition to detecting the bright bursts, the VLA observations also revealed an ongoing, persistent source of weaker radio emission in the same region which is typical of a galaxy with an active nucleus. "We do have to keep in mind that this...
