Cosmic Microwave Background

The Cosmic Microwave Background (CMB) is the afterglow of the Big Bang, providing crucial information about the early universe. Current research focuses on refining CMB observations by removing contaminating foregrounds like galactic dust, often employing advanced deep learning techniques such as diffusion models and convolutional neural networks, sometimes incorporating Bayesian approaches for uncertainty quantification. These improved analyses aim to enhance our understanding of cosmological parameters and the processes shaping the large-scale structure of the universe. The accuracy of CMB analysis directly impacts our ability to constrain cosmological models and test fundamental physics.
