The goal of this program is to advance our understanding of cosmology by studying the physics of black holes and quasars via theoretical simulations. The PI and Co-I plan to give public talks on topics related to the science of this proposal, and will develop an interactive GigaPan panoramic imaging program for the public with simulation data and Sloan Digital Sky Survey images. Broader impacts of the work also include training of graduate students.The investigators will compare state-of-the-art simulations with observational data on the quasar luminosity function and correlation function. This information will be used to estimate cosmological parameters such as primordial non-Gaussianity and normalized growth rate of structure based on the quasar correlation functions.

这个项目的目标是通过理论模拟来研究黑洞和类星体的物理特性，从而提高我们对宇宙学的理解。PI和Co-I计划就该提案的科学相关主题进行公开演讲，并将为公众开发一个交互式GigaPan全景成像程序，其中包括模拟数据和斯隆数字巡天图像。这项工作的更广泛影响还包括培养研究生。研究人员将把最先进的模拟与类星体光度函数和相关函数的观测数据进行比较。这些信息将用于估计宇宙参数，如基于类星体相关函数的原始非高斯性和归一化结构增长率。
