Penn State University
astronomers have discovered that the mysterious «cosmic whistles» known as fast
radio bursts can pack a serious punch,
in some cases releasing a billion times more energy
in gamma - rays than they do
in radio waves and rivaling the stellar cataclysms known as supernovae
in their explosive power.
Fast
radio bursts, which
astronomers refer to as FRBs, were first discovered
in 2007, and
in the years since
radio astronomers have detected a few dozen of these events.
In fact, Swift X-ray and optical observations were carried out two days after FRB 131104, thanks to prompt analysis by
radio astronomers (who were not aware of the gamma - ray counterpart) and a nimble response from the Swift mission operations team, headquartered at Penn State.
In February 2017, pinpointing the locations of FRBs will become much easier for astronomers with the commissioning of the Deep Synoptic Array prototype, an array of 10 radio dishes at Caltech's Owens Valley Radio Observatory in Californi
