由于重力镜头诱导的聚焦作用，这些颗粒的偏移经历与它们的速度正相反，因此可以在地球上检测到仅与重力相互作用的缓慢移动颗粒，从而焦距将较短。为了使它们聚焦在恒星，遥远的星系和星系等，我们都可以视为点状的来源。 〜0.01和.14倍的速度，c。放大因子可能高达约106，我们对这些颗粒的质量施加了镜头约束，以便使用大于10-9的大量磁通量来检测到它们。通过木星来限制镜头的粒子速度。
Slow-moving particles capable of interacting solely with gravity might be detected on Earth as a result of the gravitational lensing induced focusing action of the Sun. The deflection experienced by these particles is inversely proportional to the square of their velocities, and as a result their focal lengths will be shorter. We investigate the velocity dispersion of these slow-moving particles, originating from distant point-like sources, for imposing upper and lower bounds on the velocities of such particles in order for them to be focused onto Earth. Stars, distant galaxies, and cluster of galaxies, etc., may all be considered as point-like sources. We find that fluxes of such slow-moving and non-interacting particles must have speeds between ∼0.01 and .14 times the speed of light, c. Particles with speeds less than ∼0.01c will undergo way too much deflection to be focused, although such individual particles could be detected. At the caustics, the magnification factor could be as high as ∼106. We impose lensing constraints on the mass of these particles in order for them to be detected with large flux enhancements that are greater than 10−9 eV. An approximate mass density profile for Jupiter is used to constrain particle velocities for lensing by Jupiter. We show that Jupiter could potentially focus particles with speeds as low as ∼0.001c, which the Sun cannot.
