论文摘要
在观察1919年太阳日食期间遥远恒星发出的光的偏转一个世纪之后，知道实验中出现的概念以及对现代宇宙学和天体物理学的理论和观察性后果，这很有趣。除了确认爱因斯坦的引力理论外，其最大的遗产还建立了一个新的研究领域，以配音为重力镜头。紧凑型或延伸镜头的重力场对多个图像（幻影）的形成和放大是最引人注目的自然现象之一。本文介绍了第一个真正的重力透镜效应的教学观点，即双Qua QSO 0957 + 561。我们还描述了环，巨型弧，弧形，arclets和多个超新星图像的形成。令人惊讶的是，可以通过相同的技术来测量宇宙中的哈勃常数和暗物质量。最后，还简要讨论了引力波的镜头，即可能但尚未检测到的效果。
A century after observing the deflection of light emitted by distant stars during the solar eclipse of 1919, it is interesting to know the concepts emerged from the experiment and the theoretical and observational consequences for modern cosmology and astrophysics. In addition to confirming Einstein's gravitational theory, its greatest legacy was the construction of a new research area to cosmos science dubbed gravitational lensing. The formation and magnification of multiple images (mirages) by the gravitational field of a compact or extended lens are among the most striking phenomena of nature. This article presents a pedagogical view of the first genuine gravitational lens effect, the double quasar QSO 0957 + 561. We also describe the formation of rings, giant arcs, arclets and multiple Supernova images. It is also surprising that the Hubble constant and the amount of dark matter in the Universe can be measured by the same technique. Finally, the lensing of gravitational waves, a possible but still not yet detected effect, is also briefly discussed.
