    Analytical Calculation of Stokes Profiles of Rotating Stellar Magnetic Dipole
    The observation of the polarization emerging from a rotating star at different phases opens up the possibility to map the magnetic field in the stellar surface...

    Anomaly detection in Hyper Suprime-Cam galaxy images with generative adversarial networks
    The problem of anomaly detection in astronomical surveys is becoming increasingly important as data sets grow in size. We present the results of an unsupervised...

    Are solar acoustic modes correlated?
    We have studied the statistical properties of the energy of individual acoustic modes, extracted from 310 days of GOLF data near the solar minimum. The...

    Are ultra-diffuse galaxies Milky Way-sized?
    Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the...
