论文摘要
原始的黑洞具有与小行星相当的质量，是暗物质的吸引人的可能性。另外，其他形式的暗物质可能形成紧凑的暗物体（CDO）。我们从地球附近绕行的低质量黑洞或CDOS中寻找小的潮汐加速度，没有发现。使用来自德国西南部的黑森林天文台和西非北部贝宁的Djougou的超导重量表的大约10年的数据，在西非北部的Djougou上，对任何深层绕地球的最大质量设定了上限。对于半轴轴小于两个地球半径，我们排除了大于6.7x10^{13} kg的所有黑洞或CDO。较低的质量原始黑洞可能会受到鹰辐射的强烈限制。我们得出的结论是，近地球黑洞极不可能。
Primordial black holes, with masses comparable to asteroids, are an attractive possibility for dark matter. In addition, other forms of dark matter could form compact dark objects (CDO). We search for small tidal accelerations from low mass black holes or CDOs orbiting near the Earth, and find none. Using about 10 years of data from the superconducting gravimeters in the Black Forest Observatory in South-Western Germany and at Djougou, Northern Benin in Western Africa we set an upper limit on the maximum mass of any dark object orbiting the Earth as a function of orbital radius. For semi-major axis less than two earth radii we exclude all black holes or CDOs with masses larger than 6.7x10^{13} kg. Lower mass primordial black holes may be strongly constrained by Hawking radiation. We conclude that near Earth black holes are extremely unlikely.
