  • Grillo et al.
  • http://arxiv.org/abs/0711.0882
  • Combining gravitational lensing and galaxy dynamics (velocity dispersion as a funciton of radius in ellipticals) as a new and independant (!) method of measuring the geometry of the universe.
    • Way cool, if it ever gets on par in accuracy with the other methods.

  • Gibson & Schild
  • http://arxiv.org/abs/0710.5449
  • It’s about Stephans Quintet.
  • This paper made it here simply because of the über-acronym CDMHCC in the abstract. It stands for cold dark matter hierarchical clustering cosmology.
    • I have no clue about this “hydro-gravitational-dynamics” and “fluid-mechanical cosmology” though…
