中文摘要
这项合作研究的目标是对用干涉仪进行的宇宙微波背景(CMB)实验中的系统误差进行首次端到端模拟。各种各样的宇宙过程在CMB辐射上留下了微弱的极化信号,包括汤姆逊散射、引力透镜和膨胀过程中释放的引力波。对这些微弱信号的测量将决定宇宙之谜的关键部分,其中包括暴胀的能量规模和中微子的质量。检测这些小信号电平是极具挑战性的,这个程序将有助于确定最好的方法来完成这样的测量。该计划的广泛影响包括培养本科生的研究能力,以及公开发布对未来CMB实验有用的模拟结果。
英文摘要
The goal of this collaborative research is to conduct the first end-to-end simulations of systematic errors in Cosmic Microwave Background (CMB) experiments conducted with interferometers. A variety of cosmological processes have imprinted the CMB radiation with faint polarization signals, including Thomson scattering, gravitational lensing, and gravitational waves released during inflation. Measurements of these faint signals will determine key parts of the cosmological puzzle, among which are the energy scale of inflation and the masses of the neutrinos. Detecting these small signal levels is extremely challenging, and this program will help determine the best ways to accomplish such measurements.The broader impacts of this program include training of undergraduate students in research, and public release of simulations which will be useful to future CMB experiments.
