    An ionized superbubble powered by a protocluster at z = 6.5
    We show herein that a proto-cluster of Ly α emitting galaxies, spectroscopically confirmed at redshift 6.5, produces a remarkable number of ionizing continuum...

    An old, metal-poor globular cluster in Sextans A and the metallicity floor of globular cluster systems
    We report the confirmation of an old, metal-poor globular cluster (GC) in the nearby dwarf irregular galaxy Sextans A, the first GC known in this galaxy. The...

    An updated stellar census of the Quintuplet cluster
    Context. Found within the central molecular zone, the Quintuplet is one of the most massive young clusters in the Galaxy. As a consequence it offers the...

    An X-ray-quiet black hole born with a negligible kick in a massive binary within the Large Magellanic Cloud
    Stellar-mass black holes are the final remnants of stars born with more than 15 solar masses. Billions are expected to reside in the Local Group, yet only a few...

    Analysing the structure of the bulge with Mira variables
    Context. The Galactic bulge at latitude 4 < |b|(deg) < 10 was claimed to show an X-shape, which means that stellar density distributions along the line of sight...

    Analysis of absorption lines in the high-resolution spectra of five hot post-AGB candidates
    From an analysis of absorption lines in the high-resolution spectra, we have derived the radial velocities, stellar parameters (T eff, log g, wind-strength...

    Analysis of chemical abundances in planetary nebulae with [WC] central stars. I. Line intensities and physical conditions
    Context. Planetary nebulae (PNe) around Wolf-Rayet [WR] central stars ([WR]PNe) constitute a particular photoionized nebula class that represents about 10% of...

    Analysis of chemical abundances in planetary nebulae with [WC] central stars. II. Chemical abundances and the abundance discrepancy factor
    Aims: We present the abundance analysis of 12 planetary nebulae ionized by [WC]-type stars and weak-emission-line stars (wels) obtained from high-resolution...

    Analysis of integral field spectroscopy observations of the planetary nebula Hen 2-108 and its central star
    The study of planetary nebulae provides important constraints for many aspects of stellar and Galactic evolution. Hen 2-108 is a poorly known planetary nebula...
