    Millimeter Observation of the SZ Effect in the Corona Borealis Supercluster
    We have observed the Corona Borealis supercluster with the Millimeter and Infrared Testa Grigia Observatory (MITO), located in the Italian Alps, at 143, 214...

    Modelling neutral hydrogen in galaxies using cosmological hydrodynamical simulations
    The characterization of the atomic and molecular hydrogen content of high-redshift galaxies is a major observational challenge that will be addressed over the...

    Modified Newtonian Dynamics, an Introductory Review
    By the time, in 1937, the Swiss astronomer Zwicky measured the velocity dispersion of the Coma cluster of galaxies, astronomers somehow got acquainted with the...

    Multicomponent scalar dark matter at high-intensity proton beam experiments
    We study a scalar dark matter (DM) model with two DM species coupled to the standard model (SM) particles via a sub-GeV dark photon. In this model, we find that...

    New light on baryonic matter and gravity on cosmic scales
    Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic...

    nIFTy galaxy cluster simulations - I. Dark matter and non-radiative models
    We have simulated the formation of a galaxy cluster in a Λ cold dark matter universe using 13 different codes modelling only gravity and non-radiative...

    NIHAO - XIV. Reproducing the observed diversity of dwarf galaxy rotation curve shapes in ΛCDM
    The significant diversity of rotation curve (RC) shapes in dwarf galaxies has recently emerged as a challenge to Λ cold dark matter (ΛCDM): in dark matter (DM)...

    NIHAO XXI: the emergence of low surface brightness galaxies
    The existence of galaxies with a surface brightness μ lower than the night sky has been known since three decades. Yet, their formation mechanism and emergence...

    Numerical simulations of dark matter haloes produce polytropic central cores when reaching thermodynamic equilibrium
    Self-gravitating astronomical objects often show a central plateau in the density profile (core) whose physical origin is hotly debated. Cores are theoretically...
