    A New Empirical Model for the Structural Analysis of Early-Type Galaxies, and A Critical Review of the Nuker Model
    The Nuker law was designed to match the inner few (~3-10) arcseconds of predominantly nearby (
  • Publication
    A new method for age-dating the formation of bars in disc galaxies. The TIMER view on NGC1433's old bar and the inside-out growth of its nuclear disc
    The epoch in which galactic discs settle is a major benchmark for testing models of galaxy formation and evolution but remains largely unknown. Once discs...

    A New Method of Estimating the Mass-to-Light Ratio of the Ursa Minor Dwarf Spheroidal Galaxy
    Dwarf satellite galaxies undergo strong tidal forces produced by the main galaxy potential. These forces disturb the satellite and produce asymmetries in its...
  • Publication
    A new perspective on the stellar mass-metallicity relation of quiescent galaxies from the LEGA-C survey
    We investigated the stellar mass-metallicity relation (MZR) using a sample of 637 quiescent galaxies with 10.4 ≤ log(M */M ⊙) < 11.7 selected from the LEGA-C...
  • Publication
    A new reference catalogue for the very metal-poor Universe: +150 OB stars in Sextans A
    Local Group (LG) very metal-poor massive stars are the best proxy for the First Stars of the Universe and fundamental to modelling the evolution of early...

    A New spectral stellar library for population synthesis
    A new spectral stellar library designed to be included in population synthesis models is presented. The library, which has been obtained at the INT 2.5 m...
  • Publication
    A New Stellar Library in the K Band
    Stellar population synthesis models are crucial for the understanding of the large amount of data which is being gathered for galaxies at low and high redshift...
  • Publication
    A new stellar library in the region of the CO index at 2.3 μm. New index definition and empirical fitting functions
    Context: The analysis of unresolved stellar populations demands evolutionary synthesis models with realistic physical ingredients and extended wavelength...

    A new step forward in realistic cluster lens mass modelling: analysis of Hubble Frontier Field Cluster Abell S1063 from joint lensing, X-ray, and galaxy kinematics data
    We present a new method to simultaneously and self-consistently model the mass distribution of galaxy clusters that combines constraints from strong lensing...
