  1. Supernovae at High Redshift

    Distant supernovae provide a convenient tool for cosmology. As bright beacons with small variation in their peak luminosity Type Ia Supernovae can be...
    Conference paper
  2. Nuclear Activity and Galaxy Evolution

    This talk discusses the connection between nuclear activity and galaxy evolution. First, the evidence for a fundamental connection is reviewed. Then,...
    Conference paper
  3. Solar Nebulae and Replenished Dust Disks with Planets

    Having studied the primordial, protoplanetary gas disks, and older, dusty “remnant” disks in infrared-emitting (Vega-type) circumstellar systems, we...
    Conference paper
  4. Observations of Cygnus X-3 in Quiescence in the $2.4 - 12 \mu$ m Range with ISO

    We present mid-infrared spectrophotometric and imaging photometric results obtained with ISO on the peculiar X-ray binary Cygnus X-3. The...

    Conference paper
  6. Discovery of an X-Ray Outburst in an Optically Non-Active Galaxy

    The main X-ray and optical properties of a very luminous X-ray outburst source are summarized. The results are: large variability in X-ray emission...
    Conference paper
  7. The CORALIE Planet-Search Sample

    This short contribution presents a description of the CORALIE sample selection of more than 1600 dwarf stars for the planet-search programme on the...
    Conference paper
  8. On the Formation of Jets

    The phenomenology of jets associated with a variety of black hole systems is summarized, emphasizing the constraints imposed on their origin. Models...
    Conference paper
  9. Modelling Synchrotron Outbursts in 3C 273

    We present an improved approach to derive the observed evolution of a typical synchrotron outburst in 3C 273. The method consists in a simultaneous...
    Conference paper
  10. Type Ia Supernovae: Progenitors and Diversities

    A key question for supernova cosmology is whether the peak luminosities of Type Ia supernovae (SNe Ia) are sufficiently free from the effects of...
    Ken’ichi Nomoto, Tatsuhiro Uenishi, ... Mariko Kato in From Twilight to Highlight: The Physics of Supernovae
    Conference paper
  11. Evidence for Core Collapse in the Type Ib/c SN 1999ex

    We present optical and infrared spectra of SN 1999ex, which are characterized by the lack of strong hydrogen lines, weak optical He I lines, and...
    Mario Hamuy, Maximilian Stritzinger, ... Philip A. Pinto in From Twilight to Highlight: The Physics of Supernovae
    Conference paper
  12. Freeze-Out Effects in Hydrogen and Helium Lines of SN 1987A at the Early Photospheric Epoch

    We have developed a time-dependent model of ionization, excitation and energy balance of the atmosphere of SN 1987A at the photospheric epoch to...
    Victor P. Utrobin, Nikolai N. Chugai in From Twilight to Highlight: The Physics of Supernovae
    Conference paper
  13. Circumstellar Interaction Around Supernovae

    Circumstellar interaction has been observed around all types of massive star supernovae, especially at radio and X-ray wavelengths. The interaction...
    Conference paper
  14. Light Echoes in Type Ia Supernovae

    Light echoes are a promising tool to probe the environment where SNe Ia explode and an independent source of information on the progenitor’s nature....
    Conference paper
  15. Supernova Signatures in Meteorites

    This review focuses on signatures of nucleosynthesis in supernovae that can be traced via isotope abundance anomalies in meteorites. Primary examples...
    Ulrich Ott, Günter W. Lugmair in From Twilight to Highlight: The Physics of Supernovae
    Conference paper
  16. Inflection Points on the Light Curves of Type Ia Supernovae

    While the distribution of supernova absolute magnitudes at peak is often investigated, there was no systematic study of absolute light curve behavior...
    N. N. Pavliouk, D. Yu Tsvetkov in From Twilight to Highlight: The Physics of Supernovae
    Conference paper
  17. Simulations of Solar AO Systems

    In this paper, first we compare the two kinds of algorithms that are being used in solar AO systems to sense a distorted wave-front through...
