    A reappraisal of the chemical composition of the Orion nebula based on Very Large Telescope echelle spectrophotometry
    We present Very Large Telescope (VLT) UVES echelle spectrophotometry of the Orion nebula in the 3100-10400 Årange. We have measured the intensity of 555...

    A Reappraisal of the Solar Photospheric C/O Ratio
    An accurate determination of photospheric solar abundances requires detailed modeling of the solar granulation and accounting for departures from local...
  • Publication
    A recurrent nova super-remnant in the Andromeda galaxy
    The accretion of hydrogen onto a white dwarf star ignites a classical nova eruption1,2—a thermonuclear runaway in the accumulated envelope of gas, leading to...

    A Reemerging Bright Soft X-Ray State of the Changing-look Active Galactic Nucleus 1ES 1927+654: A Multiwavelength View
    1ES1927+654 is a nearby active galactic nucleus (AGN) that has shown an enigmatic outburst in optical/UV followed by X-rays, exhibiting strange variability...

    A refined analysis of the low-mass eclipsing binary system T-Cyg1-12664
    Context. The observational mass-radius relation of main sequence stars with masses between 0.3 and 1.0 M⊙ reveals deviations between the stellar radii predicted...
  • Publication
    A refined dynamical mass for the black hole in the X-ray transient XTE J1859+226
    We present two contiguous nights of simultaneous time-resolved Gran Telescopio Canarias spectroscopy and William Herschel Telescope photometry of the black hole...
  • Publication
    A refined sub-grid model for black hole accretion and AGN feedback in large cosmological simulations
    In large-scale cosmological hydrodynamic simulations simplified sub-grid models for gas accretion on to black holes and AGN feedback are commonly used. Such...
  • Publication
    A regularization term to avoid the saturation of the sigmoids in multilayer neural networks
    In this paper we propose a new method to prevent the saturation of any set of hidden units of a multilayer neural network. This method is implemented by adding...

    A remarkable feature in the giant extragalactic H II region NGC 5471
    The discovery of a very high velocity, low-intensity gas feature in the giant extragalactic H II region NGC 5471 is reported. A broad component in the emission...
