Fredagskollokvium: Cosmoglobe: A New Framework for Cosmic Microwave Background Research
Duncan Watts, postdoctoral fellow at Institute of Theoretical Astrophysics, UiO.
The search for primordial gravitational waves from polarized Cosmic Microwave Background data requires high sensitivity data, a large frequency coverage, and excellent knowledge of the instruments that took these data.
The Cosmoglobe initiative will solve this problem by jointly analyzing datasets in a global Bayesian framework, and bringing together a global community of researchers to leverage their collective knowledge and data.
In this talk, I will give updates on the collaboration and the datasets we are currently analyzing. I will close by focusing on the status of the WMAP dataset, in particular discussing differences between the original analysis and the Cosmoglobe reanalysis.
