    Detection of satellite remnants in the Galactic halo with Gaia- III. Detection limits for ultrafaint dwarf galaxies
    We present a method to identify ultrafaint dwarf galaxies (UFDGs) candidates in the halo of the Milky Way using the future Gaia catalogue and we explore its...

    Detection of the [C I] λ8727 emission line. Low-ionization structures in NGC 7009
    We report the first spatially resolved detection of the near-infrared [C I] λ8727 emission from the outer pair of low-ionization structures in the planetary...

    Detection of transit timing variations in excess of one hour in the Kepler multi-planet candidate system KOI 806 with the GTC
    Aims: We report the detection of transit timing variations (TTVs) well in excess of one hour in the Kepler multi-planet candidate system KOI 806. This system...

    Determination of the Integrated Molar Absorptivity and Molar Extinction Coefficient of Hydrogenated Fullerenes
    The integrated molar absorptivity (Psi) and the molar extinction coefficient (epsilon) of each infrared transition of the hydrogenated fullerenes (known as...
  • Publication
    Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation
    We investigate the formation of the satellite galaxy population of a Milky Way-mass halo in a very highly resolved magnetohydrodynamic cosmological zoom-in...
  • Publication
    Diagonal Ridge Pattern of Different Age Populations Found in Gaia-DR2 with LAMOST Main-sequence Turnoff and OB-type Stars
    We revisit the diagonal ridge feature (diagonal distributions in the R, v φ plane) found in Gaia and present a timing analysis for it between Galactocentric...

    Differential reddening in 48 globular clusters: An end to the quest for the intracluster medium
    For decades, it has been theorized that a tenuous but detectable intracluster medium should be present in globular clusters, which is continuously replenished...
  • Publication
    Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection
    We present high-resolution (R ~ 15 000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already...

    Dipolar dark matter simulations on galaxy scales with the RAMSES code
    We numerically explore on galaxy scales the dipolar dark matter (DM) model based on the concept of gravitational polarization. This DM model has been proposed...
