Descripción
The small and elusive Carina dSph still presents many open questions concerning its stellar populations and dynamical evolution. It presents a unique star formation history, with well separated episodes over a time of ˜10 Gyr. However, the complex star formation history does not seem to have caused a strong chemical evolution of its stellar content. Moreover, the occurrence of extra-tidal stars has not been firmly established. These might be the signature of ongoing tidal interaction with the Galaxy, or belong to a diffuse halo as suggested by recent N-body simulations. We undertook a photometric and spectroscopic investigation over a substantial fraction of the Carina body, to fully characterize its stellar content.

    Identification of Superclusters and their Properties in the Sloan Digital Sky Survey
    Superclusters are the largest massive structures in the cosmic web on tens to hundreds of megaparsecs (Mpc) scales. They are the largest assembly of galaxy clusters in the Universe. Apart from a few detailed studies of such structures, their evolutionary mechanism is still an open question. In order to address and answer the relevant questions, a

    Rapid multiwavelength variability reveals jet emission in the black hole binary V404 Cygni in quiescence
    Spitzer Space Telescope observations of several quiescent black hole low mass X-ray binaries (LMXBs) have shown mid-infrared excesses above the emission of a companion star. The excess has been proposed to originate from either a relativistic jet or circumbinary disk. If the mid-IR originates in a jet, then it probes the region closest to the black

    KIC 9163796 - Age determination by asteroseismic grid modelling for an oscillating red giant binary
    The age of a star cannot be measured but only inferred from observational quantities related to age. A wellknown stellar age greatly impacts our understanding of evolution on much larger scales, such as exoplanetary systems or the history of the Milky Way. For stars in the red-giant phase, comparison of observations with evolutionary models
