An exact cosmological solution of a Scalar-Tensor Gravity theory compatible with the $\Lambda$CDM model
exact cosmological solution Scalar-Tensor Gravity theory compatible $\Lambda$CDM model
2010/11/15
consider the massive Scalar-Tensor theory in the Jordan frame F() = K22,Z() = 1, and U() = (1/2)m22, F() corresponds to a constant Brans-Dicke parameter !BD = 1/4K2. The constaint of the solar s...
An Exact Solution of the Gamma Ray Burst Arrival Time Analysis Problem
Gamma Ray Bursts triangulation
2009/5/19
An analytical solution of the GRB arrival time analysis is
presented. The errors in the position of the GRB resulting from timing and
position errors of different satellites are calculated. A simple...
Exact Solutions of Brans-Dicke Cosmology and the Cosmic Coincidence Problem
Brans-Dicke Cosmology the Cosmic Coincidence Problem
2010/10/15
We present some cosmological solutions of Brans-Dicke theory, characterized by a decaying vacuum energy density and by a constant relative matter density. With these features, they shed light on the c...
