Interstellar Matter -- From the Solar System to QSO Absorption-Line Systems

Most of my current and planned research involves the use of high resolution optical and UV spectra to gain a detailed understanding of the interstellar gas and dust in various local environments, and then to apply that knowledge to the interpretation of the metal absorption lines seen in the spectra of distant QSO's. I am (or have been) involved in a number of projects related to those overall aims:

• Why?
• Galactic ISM
  • High-Resolution Optical Surveys
  • Detailed Line of Sight Studies
  • Translucent Clouds
  • Temporal Variability / Small-Scale Structure
  • High-Velocity Gas
  • Heavy Elements / Depletions
  • Diffuse Interstellar Bands
  • Local ISM
  • Catalogues
    • High-Resolution Spectra -- Atomic Lines
    • High-Resolution Spectra -- Molecular Lines
    • Medium-Resolution Spectra
    • Column Densities
• Magellanic Clouds ISM
  • Large Magellanic Cloud
  • Small Magellanic Cloud
  • Optical and UV Surveys
  • Catalogues
    • Optical & UV spectra
    • Column Densities
• QSO Absorption-Line Systems
  • Elemental Abundances (Gas & Dust)
    • Catalogue of QSOALS Abundances
  • Lyman Alpha Forest
