Fast Radio Bursts from neutron stars plunging into black holes

Understand

Fast radio bursts (FRBs) are millisecond-duration intense radio flares occurring at cosmological distances.

• Many models have been proposed to explain these topical astronomical events, but none has so far been confirmed.
• Here we show that a novel way involving enhanced giant radio pulses from a rapidly spun-up neutron star near a spinning black hole can explain the main properties of non-repeating FRBs.
• Independent observations of such pulses, which are not enhanced, from some Galactic pulsars make our model reliable.
