'Slide Whistle' Fast Radio Burst Observed by SETI

The repeating FRB 20220912A exhibits a unique frequency shift, challenging existing models of these cosmic phenomena.

SETI Institute scientists observed 35 explosive outbursts from a repeating 'fast radio burst' (FRB) that shifted in frequency, resembling a 'cosmic slide whistle'.
The FRB, known as FRB 20220912A, was observed using the upgraded Allen Telescope Array (ATA) at the SETI Institute.
FRBs are brief flashes of light from outside our Milky Way galaxy, believed to come from powerful objects like neutron stars with intense magnetic fields, or from cataclysmic events like the collision of stars.
The bursts of radiation from FRB 20220912A shifted down in frequency, a behavior that scientists had never seen before from an FRB.
No existing model can explain all of the properties of FRBs that have been observed so far.
