A Nongray Theory of Extrasolar Giant Planets and Brown Dwarfs
We present the results of a new series of nongray calculations of the atmospheres, spectra, colors, and evolution of extrasolar giant planets (EGPs) and brown dwarfs for effective temperatures belowExpand

Lorentz invariance and quantum gravity: an additional fine-tuning problem?
Trying to combine standard quantum field theories with gravity leads to a breakdown of the usual structure of space time at around the Planck length, 1.6x10(-35) m, with possible violations ofExpand

Dark Energy from Violation of Energy Conservation.
In this Letter, we consider the possibility of reconciling metric theories of gravitation with a violation of the conservation of energy-momentum. Under some circumstances, this can be achieved inExpand

A theoretical interpretation of the measurements of the secondary eclipses of tres-1 and HD 209458b
We calculate the planet-star flux-density ratios as a function of wavelength from 0.5 µmto 25 µmfor the transiting extrasolar giant planets TrES-1 and HD209458b and compare them with the recentExpand

Einstein-Yang-Mills isolated horizons: Phase space, mechanics, hair and conjectures
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}, {\itExpand

On the quantum origin of the seeds of cosmic structure
The current understanding of the quantum origin of cosmic structure is discussed critically. We point out that in the existing treatments a transition from a symmetric quantum state to anExpand

Shortcomings in the Understanding of why Cosmological Perturbations Look Classical
There is a persistent state of confusion regarding the account of the quantum origin of the seeds of cosmological structure during inflation. The issue is the transition from the quantumExpand

Alternative approach to the galactic dark matter problem
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 featuresExpand

Do collapsed boson stars result in new types of black holes
We prove a general no-hair theorem which is then applied to the case of a theory that consists of a number of complex scalar fields minimally coupled to gravity that vary harmonically with time andExpand

Lorentz Invariance Violation and its Role in Quantum Gravity Phenomenology
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 toExpand
