Missing channel reconstruction for sloan digital sky survey images using linear models and generative adversarial networks
… Sky Survey (SDSS) dataset, one of the largest astronomical surveys, suffers from noise and missing information in some of the image channels. This thesis implements two methods—the linear model and the deep learning model—on 12,730 SDSS images for missing channel re- construction. Specifically, …

Probabilistic photometric redshifts in the era of petascale astronomy
With the growth of large photometric surveys, accurately estimating photometric redshifts, preferably as a probability density function (PDF), and fully understanding the implicit systematic uncertainties in this process has become increasingly important. These surveys are expected to obtain images …
