摘要

对于闵科夫斯基时空平面背景上平面引力波的微扰模型，发现了引力波场中带电云的电磁辐射，并被远程观测者探测到。研究表明，云中的电荷密度没有变化，辐射是由引力波诱导的电流产生的。得出了辐射的角度分布。如果云介质的折射率大于一，则会产生切伦科夫型辐射。

Induced Electromagnetic Radiation from a Charged Cloud in a Plane Gravitational Wave

For the perturbative model of a plane gravitational wave on a flat background of Minkowski space-time, electromagnetic radiation from a charged cloud in the field of a gravitational wave, detected by a remote observer, was found. It is shown that the charge density in the cloud does not change, and the radiation is generated by currents induced by the gravitational wave. The angular distribution of the radiation is obtained. If the refractive index of the cloud medium is greater than unity, Cherenkov-type radiation is generated.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
