attolensing作为修正引力理论可能探测器的天体物理条件
Astrophysical Condition on the attolensing as a possible probe for a modified gravity theory
摘要：
我们研究了质量小于10^-19太阳质量的黑洞在引力透镜中的波动效应，这种引力透镜效应被称为attolensing，其动机是最近的一份报告，该报告认为引力透镜效应可能是膜世界假设中修正引力理论的一个可能的探索。重点讨论了有限光源尺寸效应和光源与透镜的相对运动效应对变焦距中波动效应的影响。论证了透镜干涉信号作为修正引力理论探测器的天体物理条件。文中还讨论了微透镜系统中的干涉特征。
英文摘要：
We investigate the wave effect in the gravitational lensing by a black hole with very tiny mass less than 10^-19 solar mass, which is called attolensing, motivated by a recent report that the lensing signature might be a possible probe of a modified gravity theory in the braneworld scenario. We focus on the finite source size effect and the effect of the relative motion of the source to the lens, which are influential to the wave effect in the attolensing. Astrophysical condition that the lensed interference signature can be a probe of the modified gravity theory is demonstrated. The interference signature in the microlensing system is also discussed.
