    Halo concentrations in the standard Λ cold dark matter cosmology
    We study the concentration of dark matter haloes and its evolution in N-body simulations of the standard Λ cold dark matter (ΛCDM) cosmology. The results...

    High-velocity clouds as dark matter in the Local Group
    The High-Velocity Clouds (HVCs) observed in the Galactic neighbourhood, have been proposed to be remnants of the formation of the galaxies in the Local Group...

    How Far Do They Go? The Outer Structure of Galactic Dark Matter Halos
    We study the density profiles of collapsed galaxy-size dark matter halos with masses 1011 to 5×1012 Msolar focusing mostly on the halo outer regions from the...

    How to use a cosmological N-body simulation as a theoretical model
    A key problem that we are facing in cosmology nowadays is that we cannot make accurate predictions with our current theoretical models. We have all of the...

    How well does galaxy clustering constrain cosmology?
    On the LCDM cosmology, dark matter collapses into virialised objects called haloes. The abundance and distribution of these haloes are a direct consequence of...

    Hunting down systematics in baryon acoustic oscillations after cosmic high noon
    Future dark energy experiments will require accurate theoretical predictions for the baryon acoustic oscillations (BAOs). Here, we use large N-body simulations...

    Hunting for VIPERS red nuggets - traces of the past
    Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4...

    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...

    Hα kinematics of the Spitzer Infrared Nearby Galaxies Survey - II
    This is the second part of an Hα kinematics follow-up survey of the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample. The aim of this paper is to shed new...
