The purpose of this project is to use gravitational microlensing in lensed quasars to measure the sizes of innermost quasar emission regions. The main goals will be to (1) accurately measure the scaling of accretion disk size with black hole mass; (2) determine the scaling of disk size with wavelength from the near-IR through the space UV; (3) determine the size of the non-thermal X-ray emitting regions and their scaling with black hole mass; (4) routinely measure disk inclinations and orientations; and (5) measure the changes in disk structure with changes in luminosity.Broader impacts of the work include training of graduate students and a postdoc, public lectures, and middle school teacher training by the PI.

本计画的目的是利用透镜类星体的微重力透镜效应来量测类星体最内层发射区的大小。主要目标是：（1）准确测量吸积盘大小与黑洞质量的比例关系;（2）确定吸积盘大小与从近红外到空间紫外的波长的比例关系;（3）确定非热X射线发射区的大小及其与黑洞质量的比例关系;（4）定期测量吸积盘的倾斜度和方向;（5）测量随光度变化的盘结构的变化。这项工作的广泛影响包括由PI培训研究生和博士后、公开讲座和中学教师。
