    ILLUSTRating red nugget assembly through observations and simulations
    The properties of massive and compact early-type galaxies provide important constraints on early galaxy formation processes. Among these, massive relic galaxies...
  • Publication
    Image reconstruction with analytical point spread functions
    Context. The image degradation produced by atmospheric turbulence and optical aberrations is usually alleviated using post-facto image reconstruction techniques...
  • Publication
    Impact of metallicity and star formation rate on the time-dependent, galaxy-wide stellar initial mass function
    The stellar initial mass function (IMF) is commonly assumed to be an invariant probability density distribution function of initial stellar masses. These...

    Impact of opacity effects on chromospheric oscillations inferred from NLTE inversions
    Context. Spectropolarimetric inversions are a fundamental tool for diagnosing the solar atmosphere. Chromospheric inferences rely on the interpretation of...
  • Publication
    Impact of surface dynamo magnetic fields on the solar abundance of the CNO elements
    Most studies of the solar metallicity, based on abundance determinations of the CNO elements, ignore the fact that the quiet solar photosphere is significantly...

    Impact of the Galactic bar on tidal streams within the Galactic disc. The case of the tidal stream of the Hyades
    Tidal streams of disrupted clusters are powerful probes of the gravitational potential of the Galaxy and they are routinely detected in the stellar halo of the...

    Impact of young stellar components on quiescent galaxies: deconstructing cosmic chronometers
    Context. Cosmic chronometers may be used to measure the age difference between passively evolving galaxy populations to calculate the Hubble parameter H(z) as a...

    Impact on asteroseismic analyses of regular gaps in Kepler data
    Context. The NASA Kepler mission has observed more than 190 000 stars in the constellations of Cygnus and Lyra. Around 4 years of almost continuous ultra high...

    Improved characterization of the TOI-2141 system: A dense sub-Neptune with non-transiting inner and outer companions
    Aims. We aim to refine the fundamental parameters of the TOI-2141 planetary system, which includes a transiting sub-Neptune orbiting a Sun-like star on a...
