    Learning to do multiframe wavefront sensing unsupervised: Applications to blind deconvolution
    Context. Observations from ground-based telescopes are severely perturbed by the presence of the Earth's atmosphere. The use of adaptive optics techniques has...

    Lessons learned from the two largest Galaxy morphological classification catalogues built by convolutional neural networks
    We compare the two largest galaxy morphology catalogues, which separate early- and late-type galaxies at intermediate redshift. The two catalogues were built by...

    Light-curve classification with recurrent neural networks for GOTO: dealing with imbalanced data
    The advent of wide-field sky surveys has led to the growth of transient and variable source discoveries. The data deluge produced by these surveys has...

    Line-of-sight velocity distributions of elliptical galaxies from collisionless mergers
    We analyse the skewness of the line-of-sight velocity distributions in model elliptical galaxies built through collisionless galaxy mergers. We build the models...

    Linearization versus Preconditioning: Which Approach Is Best for Solving Multilevel Transfer Problems?
    We present a critical analysis of linearization and preconditioning, the two most used approaches proposed for achieving the required linearity in the iterative...
