Do energetic pulsars produce bursts like mysterious fast radio bursts?

Astronomers compared the repeating fast radio burst FRB 20200120E, found in a globular cluster, with giant pulses from M28A, the brightest millisecond pulsar in the galaxy. The two sources show striking differences: M28A's pulses are 50 times shorter, far dimmer, regularly periodic, and broad-spectrum, while FRB 20200120E's bursts are unpredictable, narrow-band, and intense. The findings don't rule out a pulsar origin for FRBs but suggest FRB 20200120E would have to be a completely novel type with no known Galactic match.
