    IMF radial gradients in most massive early-type galaxies
    Using new long-slit spectroscopy obtained with X-Shooter at ESO-VLT, we study, for the first time, radial gradients of optical and near-infrared initial mass...

    IMF shape constraints from stellar populations and dynamics from CALIFA
    In this Paper, we describe how we use stellar dynamics information to constrain the shape of the stellar initial mass function (IMF) in a sample of 27 early...

    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...

    Implementation of feedback in smoothed particle hydrodynamics: towards concordance of methods
    We perform simulations of feedback from supernovae and black holes with smoothed particle hydrodynamics. Such strong perturbations are inaccurately handled with...

    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 for the formation of star clusters from extragalactic star formation rates
    Observations indicate that young massive star clusters in spiral and dwarf galaxies follow a relation between luminosity of the brightest young cluster and the...

    Improved CMB anisotropy constraints on primordial magnetic fields from the post-recombination ionization history
    We investigate the impact of a stochastic background of primordial magnetic fields (PMF) generated before recombination on the ionization history of the...

    Improved Hubble Space Telescope proper motions for Tycho-G and other stars in the remnant of Tycho's Supernova 1572
    With archival and new Hubble Space Telescope observations, we have refined the space-velocity measurements of the stars in the central region of the remnant of...

    Improved hydrodynamic pulsation models for the pulsating extreme helium star V652 Herculis
    New non-linear hydrodynamic models have been constructed to simulate the radial pulsations observed in the extreme helium star V652 Her. These use a finer...
