Spectral Energy Distribution

Spectral energy distribution (SED) analysis aims to characterize the distribution of energy emitted across different wavelengths by a source, providing insights into its physical properties. Current research focuses on improving the accuracy and efficiency of SED modeling, employing techniques like Bayesian analysis, neural networks (including variational autoencoders and normalizing flows), and approximate message passing algorithms to overcome challenges posed by data noise, computational cost, and ill-posed inverse problems. These advancements are impacting diverse fields, from astrophysics (analyzing protoplanetary disks and galaxy formation) to material science (controlling color appearance) and even signal processing (analyzing audio and gravitational waves), enabling more precise and efficient data analysis.
