    Binarity at LOw Metallicity (BLOeM): Multiplicity properties of Oe and Be stars
    Context. Rapidly rotating classical OBe stars have been proposed as the products of binary interactions, and the fraction of Be stars with compact companions...

    Binarity at LOw Metallicity (BLOeM): The multiplicity properties and evolution of BAF-type supergiants
    Given the uncertain evolutionary status of blue supergiant stars, their multiplicity properties hold vital clues to better understand their origin and evolution...

    Binarity at the L/T brown dwarf transition. Adaptive optics search for companions
    Context: Current atmospheric models cannot reproduce some of the characteristics of the transition between the L dwarfs with cloudy atmospheres and the T dwarfs...

    Binary frequency of planet-host stars at wide separations. A new brown dwarf companion to a planet-host star
    Aims: The aim of the project is to improve our knowledge on the multiplicity of planet-host stars at wide physical separations. Methods: We cross-matched...

    Binary star population of the Sculptor dwarf galaxy
    Aims: We aim to compute the binary fraction of "classical" dwarf spheroidal galaxies (dSphs) that are satellites of the Milky Way (MW). This value can offer...

    Black hole feeding and star formation in NGC 1808
    We report on Atacama Large Millimeter Array (ALMA) observations of CO(3−2) emission in the Seyfert2/starburst galaxy NGC 1808, at a spatial resolution of 4 pc...

    Black hole masses and starbursts in X-shaped radio sources
    It has been suggested that the X-shaped morphology observed in some radio sources can reflect either a recent merger of two supermassive black holes (SMBHs) or...

    Black hole masses for 14 gravitationally lensed quasars
    Aims: We have estimated black hole masses (M BH) for 14 gravitationally lensed quasars using Balmer lines; we also provide estimates based on MgII and CIV...

    Black hole virial masses from single-epoch photometry. The miniJPAS test case
    Context. Precise measurements of black hole masses are essential to understanding the coevolution of these sources and their host galaxies. Aims: We develop a...
