论文摘要
与标准模型光子具有动力学混合的深色光子暗物质可以在其质量$ m_ {a'} $与等离子频率相吻合的环境中共鸣。我们表明，在银河中心中的中子恒星中的这种转换或在银河中心积聚的白色矮人可以导致可检测到的无线电信号。取决于暗物质空间分布，未来的射电望远镜可能对超过电流约束的值的值敏感，该值超过了电流约束，按$ m_ {a'} \ in \ in \ left（6 \ times 10^{ - 6}，7 \ times 10^times 10^{ - 4} \ right）$ ev。
Dark photon dark matter that has a kinetic mixing with the Standard Model photon can resonantly convert in environments where its mass $m_{A'}$ coincides with the plasma frequency. We show that such conversion in neutron stars or accreting white dwarfs in the galactic centre can lead to detectable radio signals. Depending on the dark matter spatial distribution, future radio telescopes could be sensitive to values of the kinetic mixing parameter that exceed current constraints by orders of magnitude for $m_{A'} \in \left(6\times 10^{-6},7\times 10^{-4}\right)$ eV.
