The Cosmic Microwave Background (CMB) is the most ancient radiation observed, carrying primeval information of the early universe. During the past decades, the CMB observations have revealed basic properties of the universe with remarkable precision (including the age, curvature, and contents of the universe etc) Looking ahead, the CMB observations are expected to inform us much more, including the origin of the initial condition. In my talk, I will introduce the background of the CMB observations and present the design and scientific goals of several on-going CMB experiments I am involved in, including the Atacama Cosmology Telescope (ACT), the Cosmology Large Angular Scale Surveyor (CLASS), the Simons Observatory (SO), and CMB-S4.
 徐智磊： Dr. Zhi-Lei Xu is a postdoctoral researcher at the University of Pennsylvania since 2017. He graduated from the University of Science and Technology of China (USTC) in 2011 and joined the Henry A. Rowland Department of Physics & Astronomy at the Johns Hopkins University for Ph.D. study, working on the Cosmology Large Angular Scale Surveyor (CLASS), and obtained his Ph.D. in 2017. At the University of Pennsylvania, he works on Simons Observatory (SO), Atacama Cosmology Telescope (ACT), CMB-S4, and Dark Energy Survey (DES).
