Unlikely to be a coincidence
Nevertheless, the important clue was that FRBs hint the total quantity of gasoline they’ve handed via. We all know this as a result of high-frequency radio waves journey sooner via the gasoline than low-frequency waves, so the time distinction between them tells us the quantity of gasoline.
As a result of we all know the average gas density of the universe, we will relate this gasoline content material to distance, which is called the Macquart relation. And the space travelled by FRB 20190425A was a near-perfect match for the space to GW190425. Bingo!
So have we found the supply of all FRBs? No. There should not sufficient merging neutron stars within the Universe to elucidate the variety of FRBs — some should nonetheless come from magnetars, like SGR 1935+2154 did.
And even with all of the proof, there’s nonetheless a one in 200 likelihood this might all be an enormous coincidence. Nevertheless, LIGO and two different gravitational wave detectors, Virgo, and KAGRA, will turn back on in Might this yr, and be extra delicate than ever, whereas CHIME and other radio telescopes are prepared to instantly detect any FRBs from neutron star mergers.
In just a few months, we could discover out if we’ve made a key breakthrough — or if it was only a flash within the pan.
