摘要:

本文讨论了银河系内引力微透镜现象对检验引力光偏转爱因斯坦公式的可能性。为此,通过引入参数eps来修改透镜映射,该参数表征与该公式的偏差。一个简单的幂律描述的这种偏差的例子进行了分析。我们使用2018年光学引力透镜实验(OGLE)的数据形成了100个微透镜光变曲线的样本。所得eps值在1%误差内不与广义相对论矛盾。

英文摘要:

The potential of the gravitational microlensing inside our Galaxy for testing the Einstein formula for the gravitational light deflection is discussed. For this purpose, the lens mapping is modified by introducing parameter eps, which characterizes the deviation from this formula. An example of such deviation described by a simple power law is analyzed. We formed a sample of 100 microlensing light curves using the data of the Optical Gravitational Lensing Experiment (OGLE) for 2018. The resulting eps value does not contradict the General Relativity within 1 percent errors.
