Testing Modified Gravity with Gravitational Wave Astronomy
Testing Modified Gravity Gravitational Wave Astronomy
2011/1/13
The emergent area of gravitational wave astronomy promises to provide revolutionary discoveries in the areas of astrophysics, cosmology, and fundamental physics. One of the most exciting possibilities...
Future proposed satellite missions as Euclid can offer the opportunity to test general relativity on cosmic scales through mapping of the galaxy weak lensing signal. In this paper we forecast the abil...
Goldstone's Theorem and Hamiltonian of Multi-galileon Modified Gravity
Goldstone's Theorem Hamiltonian of Multi-galileon Modified Gravity
2010/11/16
The galileon model was recently proposed to locally describe a class of modi ed gravity theories,including the braneworld DGP model. We discuss spontaneous symmetry breaking of the self-accelerating b...
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
Unified cosmic history theory Lorentz non-invariant models
2010/11/16
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structure and cosm...
Topology of large scale structure as test of modified gravity
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
The genus of the iso-density contours is a robust measure of the topology of large-scale structure, and relatively insensitive to galaxies biasing and redshift-space distortions. We show that the grow...
External field effect of modified Newtonian dynamics in the Solar system
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/27
The Modified Newtonian Dynamics (MOND) has been formulated as a modification of the Poisson equation for the Newtonian gravitational field.
On the Modified Random Walk for Monte-Carlo Radiation Transfer
Instrumentation and Methods for Astrophysics
2010/12/22
Min et al. (2009) presented two complementary techniques that use the diffusion approximation to allow efficient Monte-Carlo radiation transfer in very optically thick regions: a modified random walk ...
The matter Lagrangian and the energy-momentum tensor in modified gravity with non-minimal coupling between matter and geometry
energy-momentum tensor modified gravity non-minimal coupling
2010/3/18
We show that in modified $f(R)$ type gravity models with non-minimal coupling between matter and geometry, both the matter Lagrangian, and the energy-momentum tensor, are completely and uniquely deter...
Modified gravity emerging from thermodynamics and holographic principle
law of entropy thermodynamics holographic principle
2010/3/19
We discuss three different corrections to the area law of entropy. The number of bits $N$ is then modified according to the form of entropy, and the law of gravity is obtained by using the method deve...
The theory of thermodynamics tells us the equipartition law of energy does not hold in the limit of very low temperature. It is found the Debye model is very successful in explaining the experimental ...

A MODIFIED THEORETICAL Sigma-D RELATION FOR SUPERNOVA REMNANTS：II. THE CASE OF VARIABLE TEMPERATURE WITHIN THE SUPERNOVA REMNANT
ISM supernova remnants-radiation mechanisms thermal-radio continuum ISM
2009/3/13
In this preliminary report a modification of the theoretical Σ − D
relation for supernova remnants (SNRs) in the adiabatic expansion phase is presented
in another way. As in Paper I, this modi...
A MODIFIED THEORETICAL Sigma-D RELATION FOR SUPERNOVA REMNANTS：I. THE CASE OF CONSTANT TEMPERATURE WITHIN THE SUPERNOVA REMNANT
ISM supernova remnants-radiation mechanisms thermal-radio continuum ISM
2009/3/13
We present a modification of the theoretical Σ − D relation for
supernova remnants (SNRs) in the adiabatic expansion phase. This modification
is based on the convolution of the relation first ...
