    In this paper, we have proposed, developed, and tested a novel data processing technique for calculating coherent radio emissions of particles. The technique went beyond state-of-the-art in calculation of coherent contributions of all particles in the simulations, no just a small number that is a typical approach for other methods of emission calculations.

  • Benáček, J. and Karlický, M., “Zebra stripes with high gyro-harmonic numbers,” 2022. Solar Physics, 297, 103. DOI:10.1007/s11207-022-02036-y. arXiv:2208.10131.
    The paper proposes a novel model that covers gap between observed solar radio bursts during solar flare with extremely high gyro-harmonic numbers ($>$100) of cyclotron frequency, while the state-of-the-art theoretical models show exponential decrease of the emission instability for gyro-harmonic numbers (>10). We found by numerically investigating the plasma dispersion properties that the instability can produce extremely high gyro-harmonics, but only for very high particle pitch angles to the magnetic field. We showed that such angles can be expected in some solar magnetic loop close to the solar flares.
