New results pertaining to colored static black hole solutions to the EinsteinYang-Mills equations are obtained. The isolated horizons framework is used to define the concept of Hamiltonian Horizon… (More)

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 non-rotating, non-distorted black… (More)

The Isolated Horizon formalism, together with a simple phenomenological model for colored black holes was recently used to predict a formula for the ADM mass of the solitons of the EYM system in… (More)

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 for the features… (More)

We have carefully reexamined the results of the experiment of Eotvos, Pekar, and Fekete, which compared the accelerations of various materials to the Earth. We find that the Eotvos-Pekar-Fekete data… (More)

The notion that gravitation might lead to a breakdown of standard space-time structure at small distances, and that this might affect the propagation of ordinary particles has led to a program to… (More)

We present the results of a new series of non–gray calculations of the atmospheres, spectra, colors, and evolution of extrasolar giant planets (EGPs) and brown dwarfs for effective temperatures below… (More)

Using a full frequency-dependent atmosphere code that can incorporate irradiation by a central primary star, we calculate self-consistent boundary conditions for the evolution of the radius of the… (More)

Properties of the horizon mass of hairy black holes are discussed with emphasis on certain subtle and initially unexpected features. A key property suggests that hairy black holes may be regarded as… (More)

We consider a new set of effects arising from the quantum gravity corrections to the propagation of fields, associated with fluctuations of the spacetime geometry. Using already existing experimental… (More)
