论文摘要
强力镜头是映射暗物质分布和测试宇宙学参数值的理想工具。即将进行的调查（例如欧几里得和鲁宾天文台LSST）应大大增加已知强镜系统的数量，例如，在欧几里德广泛的调查中预测的100,000多个此类系统。在此简短的研究说明中，我们预测，使用LensPop重力透镜模型，在Nancy Grace Roman Space Telescope 2000平方度调查中也将检测到约17,000个强力镜头。我们介绍了源红移，大小和大型的预测分布。尽管该调查并非主要设计为强大的镜头检测实验，但它仍将为即将到来的较浅的镜头发现项目提供大型互补目录。
Strong gravitational lensing is an ideal tool for mapping the distribution of dark matter and for testing the values of cosmological parameters. Forthcoming surveys such as Euclid and the Rubin Observatory LSST should increase the number of known strong lensing systems significantly, with for example over 100,000 such systems predicted in the Euclid wide survey. In this short research note we predict that approximately 17,000 strong gravitational lenses will also be detectible in the Nancy Grace Roman Space Telescope 2000 square degree survey, using the LensPop gravitational lensing model. We present predicted distributions in source and deflector redshifts, magnitudes, and magnifications. Although this survey is not primarily designed as a strong lensing detection experiment, it will still provide a large complementary catalogue to shallower, wider-area forthcoming lensing discovery projects.
