项目摘要
The formation and evolution of galaxies is driven primarily by the gravitational effects of the dark matter in which they are embedded. Lensing of distant galaxies by the mass associated with nearer systems offers a unique probe of the relation between galaxies and their dark matter environment. There has been much recent progress in measuring this galaxy-galaxy lensing (GGL) and more recently also galaxy-group lensing, and even better measurements will soon be provided by a new generation of wide-field imaging cameras. Quantitative interpretation of such observations is impossible without detailed numerical modeling. On small scales, GGL is sensitive to the mean mass profile of individual galaxies; on intermediate scales, it probes the galaxy content and internal structure of group and cluster halos; on large scales, it constrains the statistical relation between galaxies and dark matter. However, these aspects of the dark matter distribution affect the GGL signal on all scales and are intimately related to evolutionary processes which determine the physical properties of galaxies, hence the galaxy content of GGL surveys. We are employing a very large N-body simulation of the evolution of the dark matter distribution (the Millennium Run with ~ 1010 particles), together with galaxy formation modeling which can track the evolution of all galaxies brighter than the SMC throughout this (500h−1 Mpc)3 volume, to perform detailed simulations of GGL and galaxy-group lensing within the current concordance cosmology. By tracing light rays through this simulation we can mimic present and upcoming GGL surveys for a variety of assumptions about galaxy formation and evolution. A study of second- and higher-order auto- and cross-correlation statistics and other structure measures on our simulated galaxy + shear-field sky maps will clarify their expected signal-to-noise, their relation to the three-dimensional distribution of dark matter around galaxies, and their sensitivity to the evolutionary processes shaping the observable properties of galaxies. Such a study is required if current and future generations of GGL surveys are to test the standard paradigm, to constrain its parameters, or to show how galaxy evolution depends on dark matter environment.
星系的形成和演化主要是由它们所嵌入的暗物质的引力效应驱动的。与较近系统相关的质量对遥远星系的透镜效应为星系与其暗物质环境之间的关系提供了独特的探索。最近在测量这种星系-星系透镜(GGL)和最近的星系群透镜方面取得了很大进展,新一代宽视场成像相机将很快提供更好的测量。如果没有详细的数值模拟,对这些观测结果的定量解释是不可能的。在小尺度上,GGL对单个星系的平均质量分布很敏感;在中等尺度上,它探测星系的含量和星系团晕的内部结构;在大尺度上,它限制了星系和暗物质之间的统计关系。然而,这些方面的暗物质分布影响GGL信号在所有尺度上,并密切相关的演化过程,确定星系的物理性质,因此GGL调查的星系内容。我们正在使用一个非常大的N体模拟暗物质分布的演化(千禧年运行,~ 1010粒子),以及星系形成模型,可以跟踪所有星系的演化比SMC在整个(500 h −1 Mpc)3体积,以执行GGL和星系群透镜在当前和谐宇宙学的详细模拟。通过这种模拟追踪光线,我们可以模拟目前和即将到来的GGL调查,以获得关于星系形成和演化的各种假设。二阶和高阶自相关和互相关统计和其他结构措施的研究,我们的模拟星系+剪切场的天空地图将澄清其预期的信噪比,它们与星系周围暗物质的三维分布的关系,以及它们对形成星系的可观测性质的演化过程的敏感性。如果当前和未来几代GGL调查要测试标准范式,限制其参数,或显示星系演化如何取决于暗物质环境,则需要进行这样的研究。
