A Topological Formulation of the Standard Model
Marco Spaans
A topological theory for the interactions in Nature is presented. The theory derives from the cyclic properties of the topological manifold Q=2T^3 + 3S^1 x S^2 which has 23 intrins…
Molecular Lines as Diagnostics of High Redshift Objects
Joseph Silk, Marco Spaans
Models are presented for CO rotational line emission by high redshift starburst galaxies. The influence of the cosmic microwave background on the thermal balance and the level popu…
Molecular Hydrogen in Diffuse Interstellar Clouds of Arbitrary Three-Dimensional Geometry
Marco Spaans, David A. Neufeld
We have constructed three-dimensional models for the equilibrium abundance of molecular hydrogen within diffuse interstellar clouds of arbitrary geometry that are illuminated by ul…
Topological Dynamics and Grand Unified Theory
Marco Spaans
A formalism is presented to construct a non-perturbative Grand Unified Theory when gravitational Planck-scale phenomena are included. The fundamental object on the Planck scale is…
Star Formation and Metal Production as a Function of Redshift: The Role of the Multi-Phase ISM
Marco Spaans, Marcella Carollo
We present models of the cosmological star formation and metal production history of (proto-)galaxies with varying axis ratios. More massive and/or roughly spherical systems reach…
