    Force equation of the large-scale structure of the Universe.
    This article presents a statistical-mechanical treatment of a relationship (the force equation) between the gravitational potential for two particles and the...

    Formation of Slowly Rotating Elliptical Galaxies in Major Mergers. A Resolution Study
    We study resolution effects in numerical simulations of gas-rich (20% of the total baryonic mass) major mergers, and show that the formation of slowly-rotating...

    Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
    Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of 0.18″...

    Globular clusters as a dynamical probe of dark matter
    Gravitational dynamical friction affecting the orbits of globular clusters (GCs) was studied extensively as a possible formation mechanism for nuclear star...

    Globular clusters in modified Newtonian dynamics: velocity dispersion profiles from self-consistent models
    We test the modified Newtonian dynamics (MOND) theory with the velocity dispersion profiles of Galactic globular clusters populating the outermost region of the...

    Gravitational radiation from point masses in elliptical orbits: spectral analysis and orbital parameters
    The amplitude of the gravitational waves emitted by a binary system of arbitrary eccentricity and orientation is developed in Fourier-Bessel series. Periastron...

    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 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...

    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...
