论文摘要
随着超新星冲击扩展到太空，它可能与暗物质颗粒相撞，将它们散布到速度上，而不是比典型的暗物质速度大的数量级。如果超新星残留物与地球足够近，并且适当的年龄，则可以在直接检测实验中检测到这种高速暗物质的通量，尤其是如果暗物质通过速度依赖性操作员相互作用时。这可以使检测到无需检测到的能量太少的光线暗物质变得更容易。我们表明，单元环超新星残留物既足够近又足够的年龄来产生这种通量，因此我们为将来的实验产生了新颖的直接检测约束和敏感性。
As a supernova shock expands into space, it may collide with dark matter particles, scattering them up to velocities more than an order of magnitude larger than typical dark matter velocities in the Milky Way. If a supernova remnant is close enough to Earth, and the appropriate age, this flux of high-velocity dark matter could be detectable in direct detection experiments, particularly if the dark matter interacts via a velocity-dependent operator. This could make it easier to detect light dark matter that would otherwise have too little energy to be detected. We show that the Monogem Ring supernova remnant is both close enough and the correct age to produce such a flux, and thus we produce novel direct detection constraints and sensitivities for future experiments.
