论文摘要
暗物质可以采用深色巨大的紧凑光环对象（DMachos）的形式；即，由黑暗扇形基本粒子组成的复合物体，可能具有从普朗克尺度到太阳质量尺度的宏观质量，并且还接受了广泛的能量密度和尺寸。我们将DMACHOS与可见物质的重力相互作用集中在与重力透镜实验一致的质量 - 拉迪乌斯参数空间，以及基于宇宙微波背景（CMB）的各向异性，基于在固定固化近似中的DMACHO上的球形积分。对于具有均匀密度质量轮廓和$ \ sim 10^{ - 12} -10 \，m_ \ odot $的dmachos，我们发现DMACHO可以解释其半径的100％如果其半径高于$ \ $ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\法R\ \ odot $ \ odot $。对于高于$ 10 \的较大质量，m_ \ odot $，一个半径高于$ \ sim 1 \ sim 1 \ times 10^8 \ mbox {cm} \ times（m/100 \，m_ \ odot）^{9/2} $的dmacho与CMB可观察力一致。对于质量低于$ \ sim 10^{ - 12} \，m_ \ odot $的较轻的dmacho，仍然没有一个好的实验探测器。最后，我们指出，如果X射线和光学望远镜居住在我们太阳系附近的大分子云中，则可以观察到具有质量$ \ sim 0.1 \，m_ \ odot $的较重的dmachos，M_ \ odot $，如果它们居住在剩余的大分子云中，并且会产生普通的物质。
Dark matter could take the form of dark massive compact halo objects (dMACHOs); i.e., composite objects that are made up of dark-sector elementary particles, that could have a macroscopic mass from the Planck scale to above the solar mass scale, and that also admit a wide range of energy densities and sizes. Concentrating on the gravitational interaction of dMACHOs with visible matter, we map out the mass-radius parameter space that is consistent with gravitational lensing experiments, as well as anisotropies of the cosmic microwave background (CMB) based on the spherical accretion of matter onto a dMACHO in the hydrostatic approximation. For dMACHOs with a uniform-density mass profile and total mass in the range of $\sim 10^{-12} - 10\,M_\odot$, we find that a dMACHO could explain 100% of the dark matter if its radius is above $\approx 3$ times the Einstein radius of the lensing system. For a larger mass above $10\,M_\odot$, a dMACHO with radius above $\sim 1 \times 10^8 \mbox{cm} \times(M/100\,M_\odot)^{9/2}$ is consistent with CMB observables. For a lighter dMACHO with mass below $\sim 10^{-12}\,M_\odot$, there still is not a good experimental probe. Finally, we point out that heavier dMACHOs with masses $\sim 0.1\,M_\odot$ may be observed by X-ray and optical telescopes if they reside at rest in a large molecular cloud, nearby to our solar system, and accrete ordinary matter to emit photons.
