Maxim Lyutikov: Crab giant pulses at sub-nanosecond resolution: quantitative model of non-trivial spectrum

A model for the emission of giant pulses from the Crab pulsar is proposed by Lyutikov and is based on anomalous cyclotron resonance on the ordinary modes. His main conclusions are: 1. giant pulses come from closed field lines; 2. giant pulses are seen by chance, i.e. produced in narrow emission windows; 3. closed field lines are not dead, but populated by plasma with n >> n_{GJ}; 4. Earth analogues: magnetosperic hiss, roars.
