    Machine learning for galactic archaeology: a chemistry-based neural network method for identification of accreted disc stars
    We develop a method ('Galactic Archaeology Neural Network', GANN) based on neural network models (NNMs) to identify accreted stars in galactic discs by only...

    Machine learning for transient recognition in difference imaging with minimum sampling effort
    The amount of observational data produced by time-domain astronomy is exponentially increasing. Human inspection alone is not an effective way to identify...

    Machine-learning approaches to exoplanet transit detection and candidate validation in wide-field ground-based surveys
    Since the start of the Wide-angle Search for Planets (WASP) program, more than 160 transiting exoplanets have been discovered in the WASP data. In the past...

    Made-to-measure models of the Galactic box/peanut bulge: stellar and total mass in the bulge region
    We construct dynamical models of the Milky Way's box/peanut (B/P) bulge, using the recently measured 3D density of red clump giants (RCGs) as well as kinematic...

    Magic Constraints on γ-ray Emission from Cygnus X-3
    Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to...
