Learning Correlated Astrophysical Foregrounds with Denoising Diffusion Probabilistic Models
Karthik Prabhu, Srinivasan Raghunathan, Ethan B. Anderes +1
Extragalactic foregrounds -- most notably the Cosmic Infrared Background (CIB) and the thermal Sunyaev-Zel'dovich (tSZ) effect -- exhibit complex, non-Gaussian structure and correl…
