    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...

    Metallicity Inhomogeneities in Local Star-forming Galaxies as a Sign of Recent Metal-poor Gas Accretion
    We measure the oxygen metallicity of the ionized gas along the major axis of seven dwarf star-forming galaxies. Two of them, SDSSJ1647+21 and SDSSJ2238+14, show...

    Metallicity of Galactic RR Lyrae from Optical and Infrared Light Curves. I. Period-Fourier-Metallicity Relations for Fundamental-mode RR Lyrae
    We present newly calibrated period-φ 31-[Fe/H] relations for fundamental-mode RR Lyrae stars in the optical and, for the first time, mid-infrared. This work's...

    Metallicity of Galactic RR Lyrae from Optical and Infrared Light Curves. II. Period-Fourier-Metallicity Relations for First Overtone RR Lyrae
    We present new period-ϕ 31-[Fe/H] relations for first-overtone RRL stars (RRc), calibrated over a broad range of metallicities (-2.5 ≲ [Fe/H] ≲ 0.0) using the...

    Metallicity profiles of ultradiffuse galaxies in NIHAO simulations
    Supernovae feedback driven expansion has proven to be a viable mechanism to explain the average properties, such as size, colour, mass, and internal kinematics...
  • Publication
    Metallicity, temperature, and gravity scales of M subdwarfs
    Aims: The aim of the project is to define metallicity/gravity/temperature scales for different spectral types of metal-poor M dwarfs. Methods: We obtained...

    Metallofullerenes as potential candidates for the explanation of astrophysical phenomena
    Detection of complex organic species in space has been one of the biggest challenges of the astrophysical community since the beginning of space exploration...

    Metals from star-forming dwarfs: retention or ejection?
    We show evidences that gas outflows occur in starburst galaxies as superbubbles evolve. We then question whether hot gas will be expelled and enrich the IGM...

    Meteor studies in the framework of the JEM-EUSO program
    We summarize the state of the art of a program of UV observations from space of meteor phenomena, a secondary objective of the JEM-EUSO international...
