An alternative approach to the galactic dark matter problem
Ulises Nucamendi, Marcelo Salgado, Daniel Sudarsky
We discuss scenarios in which the galactic dark matter in spiral galaxies is described by a long range coherent field which settles in a stationary configuration that might account…
Black Holes with Zero Mass
Ulises Nucamendi, Daniel Sudarsky
We consider the spacetimes corresponding to static Global Monopoles with interior boundaries corresponding to a Black Hole Horizon and analyze the behavior of the appropriate ADM m…
Einstein-Yang-Mills Isolated Horizons: Phase Space, Mechanics, Hair and Conjectures
Alejandro Corichi, Ulises Nucamendi, Daniel Sudarsky
The concept of "Isolated Horizon" has been recently used to provide a full Hamiltonian treatment of black holes. It has been applied successfully to the cases of {\it non-rotating}…
