    FROST-CLUSTERS – II. Massive stars, binaries, and triples boost supermassive black hole seed formation in assembling star clusters
    Observations and high-resolution hydrodynamical simulations indicate that massive star clusters form through a complex hierarchical assembly. We use simulations...

    Full disk helioseismology: repetitive music and the question of gap filling
    Helioseismology requires continuous measurements of very long duration, months to years. This paper addresses the specific and limited case of full disk...

    Fully adaptive Bayesian algorithm for data analysis: FABADA
    The discovery potential from astronomical and other data is limited by their noise. We introduce a novel non-parametric noise reduction technique based on...

    Gaia early DR3 systemic motions of Local Group dwarf galaxies and orbital properties with a massive Large Magellanic Cloud
    Aims: We perform a comprehensive determination of the systemic proper motions of 74 dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia...
