Description
A a part of a general chromospheric modelling programme on late-type dwarfs, the authors searched for the spectroscopic variability in chromospheric lines associated with activity. They considered especially the α Centauri system, a very close binary system composed of a G2 V and K1 V dwarfs in order to compare them to the sun. The authors searched for the rotational modulation of the chromospheric lines in order to gain information on the surface distribution of active structures on those dwarfs.

    Single-epoch and Differential Astrometric Microlensing of Quasars
    We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars (astrometric microlensing). Our strategy is based on taking the photocenter of a region in the quasar large enough as to be insensitive to microlensing as reference to measure the centroid

    A 20 kiloparsec bipolar Lyman α outflow from a radio galaxy at z = 2.95
    The study of ionized gas kinematics in high-z active galaxies plays a key part in our understanding of galactic evolution, in an age where nuclear activity was widespread and star formation close to its peak. We present a study of TXS 0952−217, a radio galaxy at z = 2.95, using VLT/MUSE integral field optical spectroscopy as part of a project aimed

    Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal). I. The formation and evolution of the thin disc from the Gaia Catalogue of Nearby Stars
    Context. The study of the Milky Way is living a golden era thanks to the enormous high-quality datasets delivered by Gaia, and space asteroseismic and ground-based spectroscopic surveys. However, the current major challenge to reconstructing the chronology of the Milky Way is the difficulty to derive precise stellar ages for large samples of stars
