Astrophysics & Cosmology

A fundamental problem in astronomy is the 3rd dimension. At large distances the sky appears as a projected image where depth information is locked up in the sum of pixel intensities integrated along the line of sight. I have spent a couple of years working on various attempts to improve our understanding of the true 3D structure of celestial objects like HII regions & galaxies and planetary nebulae through the use of 3D photoionisation models and quantum-mechanical calculations of the populations of ions present. Another very interesting and challenging problem involves the construction of source-propagation models of cosmic rays and why the non-extensive statistical mechanics theories of Constantinos Tsallis seem to be so universal and relevant to them.
