    Hyper Suprime-Cam (HSC) project for the SUBARU telescope
    In 2006, NAOJ proposed to construct the Hyper Suprime-Cam (HSC) as a second generation instrument for Subaru telescope. This is a very wide-field camera...

    Impact of baryon physics on dark matter structures: a detailed simulation study of halo density profiles
    The back-reaction of baryons on the dark matter halo density profile is of great interest, not least because it is an important systematic uncertainty when...

    Impact of internal bremsstrahlung on the detection of γ rays from neutralinos
    We present a detailed study of the effect of internal bremsstrahlung photons in the context of the minimal supersymmetric standard models and their impact on γ...

    Implications for galaxy formation models from observations of globular clusters around ultradiffuse galaxies
    We present an analysis of Hubble Space Telescope observations of globular clusters (GCs) in six ultradiffuse galaxies (UDGs) in the Coma cluster, a sample that...

    Implications of the Intriguing Constant Inner Mass Surface Density Observed in Dark Matter Halos
    It has long been known that the observed mass surface density of cored dark matter (DM) halos is approximately constant, independently of the galaxy mass (i.e...

    Intracluster light: a luminous tracer for dark matter in clusters of galaxies
    The bulk of stars in galaxy clusters are confined within their constituent galaxies. Those stars do not trace the extended distribution of dark matter well as...

    Introducing the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) survey. A preview of the low surface brightness Universe to be unveiled by LSST
    We present the first results of the LBT Imaging of Galaxy Haloes and Tidal Structures (LIGHTS) survey. LIGHTS is an ongoing observational campaign with the 2 ×...

    ion{H}{i} study of the warped spiral galaxy NGC 5055: a disk/dark matter halo offset?
    We present a study of the ion{H}{i} distribution and dynamics of the nearby spiral galaxy NGC 5055 based on observations with the Westerbork Synthesis Radio...
