    Inferring the helium abundance of extragalactic globular clusters using integrated spectra
    The leading method for the determination of relevant stellar population parameters of unresolved extragalactic Globular Clusters is through the study of their...

    Inferring the mass of submillimetre galaxies by exploiting their gravitational magnification of background galaxies
    Dust emission at submillimetre wavelengths allows us to trace the early phases of star formation in the Universe. In order to understand the physical processes...

    Influence of baryons on the orbital structure of dark matter haloes
    We explore the dynamical signatures imprinted by baryons on dark matter haloes during the formation process using the OverWhelmingly Large Simulations (OWLS), a...

    Infrared High-resolution Integrated Light Spectral Analyses of M31 Globular Clusters from APOGEE
    Chemical abundances are presented for 25 M31 globular clusters (GCs), based on moderately high resolution (R = 22,500) H-band integrated light (IL) spectra from...

    Infrared mergers and infrared quasi-stellar objects with galactic winds - I. NGC 2623: nuclear outflow in a proto-elliptical candidate
    We present the first results of a study of the morphology, kinematics and ionization structure of infrared (IR) mergers/quasi-stellar objects (QSOs) with...

    Infrared mergers and infrared quasi-stellar objects with galactic winds - II. NGC5514: two extranuclear starbursts with LINER properties and a supergiant bubble in the rupture phase
    A study of the morphology, kinematics and ionization structure of the infrared (IR) merger NGC5514 is presented. This study is based mainly on INTEGRAL two...

    Infrared mergers and infrared quasi-stellar objects with galactic winds - III. Mrk 231: an exploding young quasi-stellar object with composite outflow/broad absorption lines (and multiple expanding superbubbles)
    We present a study of outflow (OF) and broad absorption line (BAL) systems in Mrk 231, and in similar infrared (IR) quasi-stellar objects (QSOs). This study is...

    Infrared properties of blazars: putting the GASP-WEBT sources into context
    The infrared properties of blazars can be studied from the statistical point of view with the help of sky surveys, like that provided by the Wide-field Infrared...

    Infrared Properties of Star-forming Dwarf Galaxies. I. Dwarf Irregular Galaxies in the Local Volume
    A sample of 34 dwarf irregular galaxies (dIs) in the Local Volume, most nearer than 5 Mpc, has been imaged in the near-infrared (NIR) in J and Ks at the Canada...
