This thing has intrigued very much, It would be horrible if suddenly a nearby pulsar started to emit giant pulses and scorched Earth, so I have made a bit of investigation.
The thing is that giant pulses were first detected in 1968 by Staelin; there are actually known only 4 pulsars emitting giant pulses, and one of them, the Crab pulsar emits on average a giant pulse every ten seconds. Any idea of what is the mechanism that produces giant pulses?

I think these are otherwise 'normal' pulsars that have a wobbly axis of rotation. When you catch it at just the right angle, you get a tightly focused pulse. I would be curious as to how much polarized they are.. I would guess they are strongly polarized. The pulses are, however, so brief they are hard enough just to detect.

It makes sense, Chronos. This paper is interesting because it makes a distinction between giant pulses and giant micropulses
