    The infrared to X-ray correlation spectra of unobscured type 1 active galactic nuclei
    We use new X-ray data obtained with the Nuclear Spectroscopic Telescope Array (NuSTAR), near-infrared (NIR) fluxes and mid-infrared (MIR) spectra of a sample of...

    The infrared-radio correlation of star-forming galaxies is strongly M<SUB>⋆</SUB>-dependent but nearly redshift-invariant since z ∼ 4
    Over the past decade, several works have used the ratio between total (rest 8‒1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (q...

    The initial mass function of a massive relic galaxy
    Massive relic galaxies formed the bulk of their stellar component before z ˜ 2 and have remained unaltered since then. Therefore, they represent a unique...

    The initial mass function of early-type galaxies: no correlation with [Mg/Fe]
    The initial mass function (IMF) of early-type galaxies (ETGs) has been found to feature systematic variations by both dynamical and spectroscopic studies. In...

    The Initial Mass Function of Lens Galaxies from Quasar Microlensing
    We present a new approach to studying the initial mass function (IMF) in external galaxies based on quasar microlensing observations. We use measurements of...

    The inner mass distribution of late-type spiral galaxies from <monospace>SAURON</monospace> stellar kinematic maps
    We infer the central mass distributions within 0.4-1.2 disc scalelengths of 18 late-type spiral galaxies using two different dynamical modelling approaches -...

    The Inner Ring of NGC 4736: Star Formation on a Resonant Pattern
    We revise the explanation for the ``expanding H II regions ring'' of NGC 4736. From the analysis of long-slit spectra, we identify structures within the...

    The innermost globular clusters of M87
    We present a comprehensive multiwavelength photometric analysis of the innermost (˜3 × 3 kpc2) 110 globular clusters (GCs) of M87. Their spectral energy...
