Fredagskollokvium: Optical systematics in next-generation CMB experiments
Next-generation experiments studying the cosmic microwave background (CMB) are planning to deploy tens of thousands of detector elements. This effort has the potential to dramatically improve map sensitivities and therefore advance our understanding of numerous astrophysical observables accessible at millimetre wavelengths, including a hypothesized signal from primordial gravitational waves.
This technological advancement, however, is at risk of being curtailed by subtle instrument errors that induce systematics. A predominant group of potential systematic effects are related to the optical systems (the telescopes).
In this talk, I will introduce the key upcoming CMB experiments of the next decade, discuss various optical modeling techniques that inform the design of these experiments, and discuss how those techniques will influence future data analysis efforts.
