摘要

我们考虑银河系中暗物质、暗光子和自由电子之间的汤姆逊过程。其结果是可以用当前或未来的射电望远镜阵列探测到的无线电信号背景。特别地，我们计算了阿塔卡马大型毫米波阵列射电望远镜和未来的平方公里阵列的灵敏度前景，得出结论，可以探测大范围暗光子质量的无约束参数空间。2025年由美国物理学会出版

Dark photon dark matter radio signal from the Milky Way electron density

We consider Thomson-like processes between dark matter dark photons and free electrons in the Milky Way. The result is a radio signal background that can be detectable with current or future radio telescope arrays. In particular, we computed sensitivity prospects for the Atacama Large Millimeter Array radio telescope and for the future Square Kilometer Array, concluding that unconstrained parameter space in a wide range of dark photon masses can be probed.
