abstract

We study graviton-photon conversion in magnetosphere of a pulsar and explore the possibility of detecting high frequency gravitational waves with pulsar observations. It is shown that conversion of one polarization mode of photons can be enhanced significantly due to strong magnetic fields around a pulsar. We also constrain stochastic gravitational waves in frequency range of $10^{8}-10^{9}\,$Hz and $10^{13}-10^{27}\,$Hz by using data of observations of the Crab pulsar and the Geminga pulsar. Our method widely fills the gap among existing high frequency gravitational wave experiments and boosts the frequency frontier in gravitational wave observations.

    gr-qc 2025-07 accept novelty 7.0 of 10

    In a 3D treatment of the inverse Gertsenshtein effect, an isotropic unpolarized gravitational wave background scattering off a dipolar magnetic field yields partially linearly polarized radio emission, with peak inten...

    A Coleman-Weinberg correction that cancels the inflaton's quadratic term at the potential minimum triggers quartic self-resonance and a peaked GW background at 10^8-10^10 Hz; a negative quadratic term instead gives a ...
