Molecules in Galaxies at all redshifts

• 1. How to observe the H2 component?
  why cold H2 molecule invisible. Infrared H2 lines
  CO tracer. Isotopes. Virial conditions.
  CO/H2 conversion ratio
• 2. Molecular component of the Milky Way
  Molecular surveys, distances, mapping

• 3. Fractal structure
  Size-line-width relations, Mass to size,
  Statistical properties
• 4. Equilibrium, stability of molecular disks
  Formation of the fractal structure
  Shear, turbulence
• 5. External galaxies, Observations of H2 component
  Statistical properties, comparison with HI gas and other tracers.
  Relation to star formation
