Abstract:
The observation of Cosmic Microwave Background (CMB) has a central role in modern cosmology. The Simons Observatory (SO) is a new project for CMB observations, which started taking data recently in Atacama, Chile. The SO will provide us with unprecedented sensitivities in CMB polarization measurements. A super-wide field of view and its large survey area allow the SO to perform various cross-correlation analyses with other projects, including the Rubin Observatory, DESI, Euclid, Roman, CCAT-Prime, and SPHEREx. The SO's super-wide survey will also lead to follow-up observation proposals at ALMA. In this talk, after a short review of CMB observations and future projects, I will describe rich astronomical and cosmological topics at the SO, including early universe, relic particles, neutrino mass, galaxy evolution, blazars, galactic science, planet 9, and transient sources. In the end, I will discuss a way for the Taiwanese astronomy/cosmology community to participate in and contribute to the science at the SO.
