    Diffusion of Solar Magnetic Elements up to Supergranular Spatial and Temporal Scales
    The study of spatial and temporal scales on which small magnetic structures (magnetic elements) are organized in the quiet Sun may be approached by determining...

    Digging deeper into NGC 6868 II: ionized gas and excitation mechanism
    We studied the ionized gas in the inner region ( $\sim$ $680\times 470$ pc 2) of the galaxy NGC 6868 using Gemini/GMOS (Gemini Multi-Object Spectrograph)...

    Digging into the surface of the icy dwarf planet Eris
    We describe optical spectroscopic observations of the icy dwarf planet Eris with the 6.5-m MMT telescope and the Red Channel Spectrograph. We report a...
  • Publication
    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...

    Dips and eclipses in the X-ray binary Swift J1858.6-0814 observed with NICER
    We present the discovery of eclipses in the X-ray light curves of the X-ray binary Swift J1858.6-0814. From these, we find an orbital period of $P=76841.3_{-1.4...
  • Publication
    Direct Confirmation of Two Pattern Speeds in the Double-barred Galaxy NGC 2950
    We present the surface photometry and stellar kinematics of NGC 2950, which is a nearby and undisturbed SB0 galaxy hosting two nested stellar bars. We use the...
  • Publication
    Direct Imaging Explorations for Companions around Mid-Late M Stars from the Subaru/IRD Strategic Program
    The Subaru telescope is currently performing a strategic program (SSP) using the high-precision near-infrared (NIR) spectrometer IRD to search for exoplanets...

    Direct Imaging of Fine Structure in the Chromosphere of a Sunspot Umbra
    High-resolution imaging observations from the Hinode spacecraft in the Ca II H line are employed to study the dynamics of the chromosphere above a sunspot. We...
  • Publication
    Direct observation of structure in the cosmic microwave background
    Temperature fluctuations in the cosmic microwave background are a key prediction of cosmological models of structure formation in the early Universe. Ground...
