    XMM-Newton observations of the Lockman Hole. III. A relativistic Fe line in the mean X-ray spectra of type-1 and type-2 AGN
    Using the 770 ks XMM-Newton survey of the Lockman Hole field in combination with extensive optical identifications of the AGN population, we derive an average...

    XMM-Newton study of six massive, X-ray luminous galaxy cluster systems in the redshift range z = 0.25-0.5
    Massive galaxy clusters are interesting astrophysical and cosmological objects to study, but they are relatively rare. In the redshift range z = 0.25-0.5 which...

    XMMU J134736.6+173403: an eclipsing LMXB in quiescence or a peculiar AGN?
    Aims:We report the discovery of a peculiar object observed serendipitously with XMM-Newton. We present its timing and spectral properties and investigate its...

    Young nearby open clusters and their luminosity functions
    Context. Open clusters are groups of coeval stars sharing properties such as distance and metallicity, and they are key to understanding stellar evolution. Aims...

    Young T-dwarf candidates in IC 348
    Context: The determination of the lower-end of the initial mass function (IMF) provides strong constraints on star formation theories. Aims: We report here on a...

    Young [α/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?
    We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [α/Fe] abundance ratios (as determined from APOGEE spectra)...

    Young, metal-enriched cores in early-type dwarf galaxies in the Virgo cluster based on colour gradients
    Early-type dwarf galaxies are not simply featureless, old objects, but were found to be much more diverse, hosting substructures and a variety of stellar...

    z-GAL: A NOEMA spectroscopic redshift survey of bright Herschel galaxies. I. Overview
    Using the IRAM NOrthern Extended Millimetre Array (NOEMA), we conducted a Large Programme (z-GAL) to measure redshifts for 126 bright galaxies detected in the...
