摘要

我们研究了地球、银河系和星系际区域磁场中的引力子-光子转换。要求引力子转换的光子通量不超过望远镜观测到的光子通量，我们推导出频率范围在107Hz到1035Hz的随机引力波的上限。值得注意的是，在1018-1023赫兹的频率范围内，h2ΩGW的上限在特定情况下可能小于1。利用望远镜探测引力波将为高频引力波观测开辟一条新途径。

Gravitational wave search through electromagnetic telescopes

We study the graviton-photon conversion in the magnetic fields of the Earth, the Milky Way Galaxy, and intergalactic regions. Requiring that the photon flux converted from gravitons does not exceed the observed photon flux with telescopes, we derive upper limits on the stochastic gravitational waves in frequency ranges from 107Hz to 1035Hz. Remarkably, the upper limits on h2ΩGW could be less than unity in the frequency range of 1018-1023 Hz in a specific case. The detection of gravitational waves using telescopes would open up a new avenue for high frequency gravitational wave observations.

期刊介绍： Progress of Theoretical and Experimental Physics (PTEP) is an international journal that publishes articles on theoretical and experimental physics. PTEP is a fully open access, online-only journal published by the Physical Society of Japan. PTEP is the successor to Progress of Theoretical Physics (PTP), which terminated in December 2012 and merged into PTEP in January 2013. PTP was founded in 1946 by Hideki Yukawa, the first Japanese Nobel Laureate. PTEP, the successor journal to PTP, has a broader scope than that of PTP covering both theoretical and experimental physics. PTEP mainly covers areas including particles and fields, nuclear physics, astrophysics and cosmology, beam physics and instrumentation, and general and mathematical physics.
