    Conference paper
  2. Extracting Knowledge from Very Large Datasets in a Multi-Wavelength Context

    The ability to extract knowledge from very large data catalogues resulting from sky surveys or from deep wide fields, observed at various wavelength...
    Daniel Egret in Mining the Sky
    Conference paper
  3. OPTICON and the Virtual Observatory

    The challenges of multi-wavelength astrophysics require new outlooks from those appropriate to traditional astronomy. The next generation of research...
