来自火流星照相机网络的宏观暗物质约束
Macroscopic Dark Matter Constraints from Bolide Camera Networks
摘要：
宏观暗物质（宏）是粒子暗物质的一大类替代候选者。这些候选者将主要通过弹性散射传递能量，如果宏穿过大气层，这种线性能量沉积将产生可观测的信号。我们生产的约束，低质量的宏从零观测火流星形成的一个路过的宏，在两个广泛的网络，最初建立的相机观察陨石。参数空间，可以探测与计划升级到现有阵列的摄像机在这些网络之一，目前仍在使用，在澳大利亚的沙漠火球网络，估计。
英文摘要：
Macroscopic dark matter (macros) are a broad class of alternative candidates to particle dark matter. These candidates would transfer energy primarily through elastic scattering, and this linear energy deposition would produce observable signals if a macro were to pass through the atmosphere. We produce constraints for low mass macros from the null observation of bolides formed by a passing macro, across two extensive networks of cameras built originally to observe meteorites. The parameter space that could be probed with planned upgrades to the existing array of cameras in one of these networks still currently in use, the Desert Fireball Network in Australia, is estimated.
