    Merging Process and Tidal-induced Star Formation in the Ultraluminous Infrared Galaxy IRAS 08572+3915
    Integral field optical spectroscopy using the INTEGRAL system, complemented with HST imaging, has been used to characterize the merging process giving rise to...

    Metal-line emission from the warm-hot intergalactic medium - I. Soft X-rays
    Emission lines from metals offer one of the most promising ways to detect the elusive warm-hot intergalactic medium (WHIM; 105 T 107K), which is thought to...

    Metal-line emission from the warm-hot intergalactic medium - II. Ultraviolet
    Approximately half the baryons in the local Universe are thought to reside in the warm-hot intergalactic medium (WHIM), i.e. diffuse gas with temperatures in...

    Metal-rich Planetary Nebulae in the Outer Reaches of M31
    Spectroscopic data of two relatively [O III]-luminous planetary nebulae (PNe) have been obtained with the 10.4 m Gran Telescopio Canarias. M174 and M2496 are...

    Metallicities, Age-Metallicity Relationships, and Kinematics of Red Giant Branch Stars in the Outer Disk of the Large Magellanic Cloud
    The outer disk of the Large Magellanic Cloud (LMC) is studied in order to unveil clues about its formation and evolution. Complementing our previous studies in...

    Metallicity gradients in dwarf elliptical galaxies
    We discuss the relations between the metallicity gradients and the other characteristics of a set of dwarf elliptical galaxies in different environments. We...

    Metallicity gradients of disc stars for a cosmologically simulated galaxy
    We analyse for the first time the radial abundance gradients of the disc stars of a disc galaxy simulated with our three-dimensional, fully cosmological...

    Metallicity Gradients Through Disk Instability: A Simple Model for the Milky Way's Boxy Bulge
    Observations show a clear vertical metallicity gradient in the Galactic bulge, which is often taken as a signature of dissipative processes in the formation of...

    Metallicity gradients: Mass dependency in dwarf elliptical galaxies
    The formation and evolution of galaxies is imprinted on their stellar population radial gradients. Two recent articles present conflicting results concerning...
