    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...

    Metallicities in M dwarfs: Investigating different determination techniques
    Deriving metallicities for solar-like stars follows well-established methods, but for cooler stars such as M dwarfs, the determination is much more complicated...

    Metallicity effect on stellar granulation detected from oscillating red giants in open clusters
    Context. The effect of metallicity on the granulation activity in stars, and hence on the convective motions in general, is still poorly understood. Available...

    Metallicity gradient of the thick disc progenitor at high redshift
    We have developed a novel Markov Chain Monte Carlo chemical 'painting' technique to explore possible radial and vertical metallicity gradients for the thick...

    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...

    MHDSTS: a new explicit numerical scheme for simulations of partially ionised solar plasma
    The interaction of plasma with magnetic field in the partially ionised solar atmosphere is frequently modelled via a single-fluid approximation, which is valid...

    Mid-infrared imaging- and spectro-polarimetric subarcsecond observations of NGC 1068
    We present subarcsecond 7.5-13 μm imaging- and spectro-polarimetric observations of NGC 1068 using CanariCam on the 10.4-m Gran Telescopio CANARIAS. At all...

    Mid-infrared Spectral Variability Atlas of Young Stellar Objects
    Optical and near-infrared variability is a well-known property of young stellar objects. However, a growing number of recent studies claim that a considerable...
