    Large-scale variability in macroturbulence driven by pulsations in the rapidly rotating massive star ζ Oph from high-cadence ESPRESSO spectroscopy and TESS photometry
    Despite their importance, the dynamical properties of massive stars remain poorly understood. Rotation is a key driver of internal mixing and angular momentum...

    LEGUS Discovery of a Light Echo Around Supernova 2012aw
    We have discovered a luminous light echo around the normal Type II-Plateau Supernova (SN) 2012aw in Messier 95 (M95; NGC 3351), detected in images obtained...

    Life in the fast lane: a direct view of the dynamics, formation, and evolution of the Milky Way's bar
    Studies of the ages, abundances, and motions of individual stars in the Milky Way provide one of the best ways to study the evolution of disc galaxies over...

    Light elements Na and Al in 58 bulge spheroid stars from APOGEE
    We identified a sample of 58 candidate stars with metallicity [Fe/H] ≲ -0.8 that likely belong to the old bulge spheroid stellar population, and analyse their...

    Light-curve Recovery with Rubin-LSST. II. Unveiling the Darkness of the Galactic Bulge (VESTALE) with RR Lyrae
    This work is part of VESTALE, a project initiated within the Legacy Survey of Space and Time (LSST) Cadence Strategy Optimization Process. Its goal is to...

    Limited impact of jet-induced feedback in the multi-phase nuclear interstellar medium of 4C12.50
    Context. 4C12.50 (IRAS 13451+1232) at z = 0.122 is an ultraluminous infared radio galaxy that has often been proposed as a prime candidate for the link between...

    Linking bIrth and death: an Empirical approach To lumInous blue Massive star Evolution
    Recent investigations have dented confidence in state-of-the-art models of massive star evolution. As a result, our current understanding of how massive stars...
