TeVeS uses a dynamical vector field with timelike unit-norm constraint to specify a preferred local frame. When matter moves slowly in this frame\char22{}the so-called quasistatic regime\char22{}modified Newtonian dynamics results. Theories with such vectors (such as Einstein-Aether) are prone to the vector dynamics forming singularities that render their classical evolution problematic. Here, we analyze the dynamics of the vector in TeVeS in various situations. We begin by analytically showing… Expand
Geometry of modified Newtonian dynamics
Modified Newtonian Dynamics is an empirical modification to Poisson's equation which has had success in accounting for the `gravitational field' $\Phi$ in a variety of astrophysical systems. TheExpand
Numerical general relativity in exotic settings
In this thesis, we discuss applications of numerical relativity in a variety of complex settings. After introducing aspects of black hole physics, extra dimensions, holography, and Einstein-AetherExpand
Vector field models of inflation and dark energy
We consider several new classes of viable vector field alternatives to the inflaton and quintessence scalar fields. Spatial vector fields are shown to be compatible with the cosmological anisotropyExpand
On the problem of deformed spherical systems in Modified Newtonian Dynamics
Based on Newtonian dynamics, observations show that the luminous masses of astrophysical objects that are the size of a galaxy or larger are not enough to generate the measured motions which theyExpand
Stellar Oscillations in Tensor-Vector-Scalar Theory
An alternative theory of gravity has recently been proposed by Bekenstein, named tensor-vector-scalar (TeVeS) theory, which can explain many galactic and cosmological observations without the needExpand
Vector-Galileon-Tensor theories of gravity
A detailed study of the cosmological evolution in a particular vector-tensor theory of gravity with a potential and a Galileon-motivated interaction terms is presented. The evolution of vector fieldExpand
Hamiltonian Map to Conformal Modification of Spacetime Metric: Kaluza-Klein and TeVeS
It has been shown that the orbits of motion for a wide class of non-relativistic Hamiltonian systems can be described as geodesic flows on a manifold and an associated dual by means of a conformalExpand
Wave propagation and shock formation in the most general scalar-tensor theories
This work studies wave propagation in the most general scalar-tensor theories, particularly focusing on the causal structure realized in these theories and also the shock formation process induced byExpand
Preferred frame parameters in the tensor-vector-scalar theory of gravity and its generalization
The tensor-vector-scalar theory of gravity, which was designed as a relativistic implementation to the modified dynamics paradigm, has fared quite well as an alternative to dark matter, on bothExpand
TOPICAL REVIEW: The tensor-vector-scalar theory and its cosmology
Over the last few decades, astronomers and cosmologists have accumulated vast amounts of data clearly demonstrating that our current theories of fundamental particles and of gravity are inadequate toExpand


Black holes in the tensor-vector-scalar theory of gravity and their thermodynamics
Tensor-vector-scalar (TeVeS) theory, a relativistic theory of gravity, was designed to provide a basis for the modified Newtonian dynamics. Since TeVeS differs from general relativity (e.g., it hasExpand
Spherically symmetric, static spacetimes in a tensor-vector-scalar theory
Recently, a relativistic gravitation theory has been proposed [J. D. Bekenstein, Phys. Rev. D 70, 083509 (2004)] that gives the modified Newtonian dynamics in the weak acceleration regime. The theoryExpand
Dynamics of gravity in a Higgs phase
We investigate the universal low-energy dynamics of the simplest Higgs phase for gravity, `ghost condensation.' We show that the nonlinear dynamics of the `ghostone' field dominate for allExpand
Relativistic modified Newtonian dynamics from string theory
Abstract We argue that TeVeS-like vector fields appear naturally in certain string theory backgrounds involving D0-branes, as a result of the recoil velocity field, expressing the interaction ofExpand
Gravity with a dynamical preferred frame
We study a generally covariant model in which local Lorentz invariance is broken "spontaneously" by a dynamical unit timelike vector field $u^a$---the "aether". Such a model makes it possible toExpand
Theoretical Aspects of Gravitational Lensing in TeVeS
Since Bekenstein's creation of his tensor-vector-scalar theory (TeVeS), the modified Newtonian dynamics (MOND) paradigm has been redeemed from the embarrassment of lacking a relativistic version. OneExpand

Following the method developed by Chandrasekhar, a variational base for determining the eigenfrequencies of the perturbations is found and allows one to find numerically an upper bound for the central density where dynamical instability occurs. Expand
Modified Newtonian dynamics habitats within the solar system
MOdified Newtonian Dynamics (MOND) is an interesting alternative to the presence of dark matter in galaxies. We here examine the possibility that mild or even strong MOND behavior may become evidentExpand
Relativistic gravitation theory for the MOND paradigm
The modified newtonian dynamics (MOND) paradigm of Milgrom can boast of a number of successful predictions regarding galactic dynamics; these are made without the assumption that dark matter plays aExpand
