    A detailed non-LTE analysis of LB-1: Revised parameters and surface abundances
    Context. It has recently been proposed that LB-1 is a binary system at 4 kpc consisting of a B-type star of 8 M ☉ and a massive stellar black hole (BH) of 70 M...

    A detailed study of the H ii region M 43 and its ionizing star
    Aims: We have selected the Galactic H ii region M 43, a close-by apparently spherical nebula ionized by a single star (HD 37061, B0.5 V) to investigate several...
  • Publication
    A detailed study of the very high-energy Crab pulsar emission with the LST-1
    Context. To date, three pulsars have been firmly detected by imaging atmospheric Cherenkov telescopes (IACTs). Two of them reached the TeV energy range...
  • Publication
    A detailed two-dimensional stellar population study of M32
    We present integral field spectroscopy of the 9×12arcsec2 circumnuclear region of M32 obtained with the 2D_FIS fibre optics spectrographs installed at the 4.2-m...
  • Publication
    A Detection of Sgr A* in the Far Infrared
    We report the first detection of the Galactic Center massive black hole, Sgr A*, at 100 μm and 160 μm. Our measurements were obtained with PACS on board the...
  • Publication
    A detection of the donor star of Aquila X-1 during its 2004 outburst?
    Phase-resolved high-resolution optical spectroscopy has revealed narrow NIII and HeII emission lines from the soft X-ray transient Aquila X-1 during its 2004...
  • Publication
    A determination of the space density and birth rate of hydrogen-line (DA) white dwarfs in the Galactic plane, based on the UVEX survey
    We present a determination of the average space density and birth rate of hydrogen-line (DA) white dwarfs within a radius of 1 kpc around the Sun, based on an...
