GERLUMPH数据发布2：25亿个模拟微透镜光变曲线
GERLUMPH Data Release 2: 2.5 billion simulated microlensing light curves
摘要：
在即将到来的天气学全天巡天天文学时代，预计将发现和定期监测数千个新的多重成像类星体。来自引力透镜类星体图像的光变曲线进一步受到微透镜效应叠加变化的影响。为了将微透镜效应与光变曲线的固有可变性分开，必须精确测量多个图像之间的时间延迟。由此产生的微透镜光变曲线可以被分析，以揭示有关背景源的信息，例如类星体吸积盘的大小。在本文中，我们提出了最广泛的和连贯的收集模拟微透镜光变曲线，我们已经产生了$>2.5$十亿光变曲线使用GERLUMPH高分辨率微透镜放大率地图。我们的模拟可用于：训练算法来测量透镜类星体的时间延迟，规划未来的监测活动，并研究整个参数空间的光变曲线特性。我们的数据向社区开放，并通过http://gerlumph.swin.edu.au上的在线eResearch工具进行补充。
英文摘要：
In the upcoming synoptic all--sky survey era of astronomy, thousands of new multiply imaged quasars are expected to be discovered and monitored regularly. Light curves from the images of gravitationally lensed quasars are further affected by superimposed variability due to microlensing. In order to disentangle the microlensing from the intrinsic variability of the light curves, the time delays between the multiple images have to be accurately measured. The resulting microlensing light curves can then be analyzed to reveal information about the background source, such as the size of the quasar accretion disc. In this paper we present the most extensive and coherent collection of simulated microlensing light curves; we have generated $>2.5$ billion light curves using the GERLUMPH high resolution microlensing magnification maps. Our simulations can be used to: train algorithms to measure lensed quasar time delays, plan future monitoring campaigns, and study light curve properties throughout parameter space. Our data are openly available to the community and are complemented by online eResearch tools, located at http://gerlumph.swin.edu.au .
