    Microlensing toward Crowded Fields: Theory and Applications to M31
    We present a comprehensive treatment of the pixel-lensing theory and apply it to lensing experiments and their results toward M31. Using distribution functions...

    Microlensing-based Estimate of the Mass Fraction in Compact Objects in Lens Galaxies
    We estimate the fraction of mass that is composed of compact objects in gravitational lens galaxies. This study is based on microlensing measurements (obtained...

    Milky Way Satellite Census. IV. Constraints on Decaying Dark Matter from Observations of Milky Way Satellite Galaxies
    We use a recent census of the Milky Way (MW) satellite galaxy population to constrain the lifetime of particle dark matter (DM). We consider two-body decaying...

    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...

    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...
