  • Publication
    Faint object classification using Artificial Neural Networks.
    We propose a method to classify faint objects from digital astronomical images based on a layered feedforward neural network which has been trained by the...
  • Publication
    Faint recombination lines in Galactic PNe with a [WC] nucleus
    Aims: We present spatially resolved high-resolution spectrophotometric data for the planetary nebulae PB 8, NGC 2867, and PB 6. We have analyzed two knots in...
  • Publication
    Families of galaxies in the mu(e)-R(e) plane
    On the basis of a sample of Virgo cluster galaxies in a larger set of heterogeneous literature data, it is shown that ellipticals, early-type dwarfs, and bulges...
  • Publication
    Far infrared (terahertz) spectroscopy of a series of polycyclic aromatic hydrocarbons and application to structure interpretation of asphaltenes and related compounds
    A series of 33 different polycyclic aromatic hydrocarbons (PAHs) were studied by far infrared spectroscopy (terahertz spectroscopy) in the spectral range...
  • Publication
    Far infrared spectroscopy and other spectral and thermal properties of [Li@C60]PF6
    The endohedral fullerene [Li@C60]+PF6− was characterized by differential scanning calorimetry (DSC), by electronic absorption spectroscopy in the spectral range...
  • Publication
    Far- and mid-infrared spectroscopy of complex organic matter of astrochemical interest: coal, heavy petroleum fractions and asphaltenes
    The coexistence of a large variety of molecular species (i.e. aromatic, cycloaliphatic and aliphatic) in several astrophysical environments suggests that...
  • Publication
    Far-infrared constraints on the contamination by dust-obscured galaxies of high-z dropout searches
    The spectral energy distributions (SED) of dusty galaxies at intermediate redshift may look similar to very high-redshift galaxies in the optical/near infrared...
  • Publication
    Far-infrared Imaging of Post-asymptotic Giant Branch Stars and (Proto)-planetary Nebulae with the AKARI Far-Infrared Surveyor
    By tracing the distribution of cool dust in the extended envelopes of post-asymptotic giant branch stars and (proto)-planetary nebulae ((P)PNe), we aim to...
  • Publication
    Far-infrared imaging, polarimetry, and spectrophotometry on the Infrared Space Observatory
    The Infrared Space Observatory (ISO) photometer is one of four instruments on-board the European Space Agency ISO scheduled for launch in September 1995. It...
