Magnetospheric curvature radiation by bunches as emission mechanism for repeating fast radio bursts

WY Wang, YP Yang, CH Niu, R Xu… - The Astrophysical …, 2022 - iopscience.iop.org
Coherent curvature radiation as the radiation mechanism for fast radio bursts (FRBs) has
been discussed since FRBs were discovered. We study the spectral and polarization …

Polarization of magnetospheric curvature radiation in repeating fast radio bursts

WY Wang, JC Jiang, K Lee, R Xu… - Monthly Notices of the …, 2022 - academic.oup.com
Fast radio bursts (FRBs) can exhibit a wide variety of polarization properties, not only
between sources but also from burst to burst for a same one. In this work, we revisit the …

Model of pulsar pair cascades in non-uniform electric fields: Growth rate, density profile, and screening time

F Cruz, T Grismayer, S Iteanu, P Tortone… - Physics of Plasmas, 2022 - pubs.aip.org
Time-dependent cascades of electron–positron pairs are thought to be the main source of
plasma in pulsar magnetospheres and a primary ingredient to explain the nature of pulsar …

Streaming instability in neutron star magnetospheres: No indication of soliton-like waves

J Benáček, PA Muñoz, J Büchner, A Jessner - Astronomy & Astrophysics, 2024 - aanda.org
Context. Coherent radiation of pulsars, magnetars, and fast radio bursts could, in theory, be
interpreted as radiation from solitons and soliton-like waves. Solitons are meant to contain a …

Particle-in-cell simulations of electron–positron cyclotron maser forming pulsar radio zebras

M Labaj, J Benáček, M Karlický - Astronomy & Astrophysics, 2024 - aanda.org
Context. The microwave radio dynamic spectra of the Crab pulsar interpulse contain fine
structures represented via narrowband quasiharmonic stripes. The pattern significantly …

Linear acceleration emission of pulsar relativistic streaming instability and interacting plasma bunches

J Benáček, PA Muñoz, J Büchner, A Jessner - Astronomy & Astrophysics, 2023 - aanda.org
