Estimation of xi parameter on the Moffat Gravity
Estimation xi parameter the Moffat Gravity
2012/2/23
Scalar Tensor Vector Gravity(STVG) is one of modified gravity theories developed by John Moffat(2005). MOG is abbreviated name for this theory.It can explain a galactic rotation curve and the structur...
Non-relativistic Extended Gravity and its applications across different astrophysical scales
Non-relativistic Extended Gravity applications different astrophysical scales
2012/2/23
Using dimensional analysis techniques we present an extension of Newton's gravitational theory built under the assumption that Milgrom's acceleration constant is a fundamental quantity of nature. The ...
Noether symmetry for Gauss-Bonnet dilatonic gravity
Noether symmetry Gauss-Bonnet dilatonic
2011/9/27
Noether symmetry for Gauss-Bonnet-Dilatonic interaction exists for a constant dilatonic scalar potential and a linear functional dependence of the coupling parameter on the scalar field. The symmetry ...
Fourth-order gravity as the inflationary model revisited
Fourth-order gravity inflationary model
2010/3/19
We revisit the simplest (fourth-order or quadratically generated) modified gravity model in four space-time dimensions. It is equivalent to the certain quintessence model via a Legendre-Weyl transform...
Ghost anomalous dimension in asymptotically safe quantum gravity
ghost anomalous dimension quantum gravity
2010/3/22
We compute the ghost anomalous dimension within the asymptotic-safety scenario for quantum gravity. For a class of covariant gauge fixings and using a functional RG scheme, the anomalous dimension $\e...
Alternatives to dark matter: Modified gravity as an alternative to dark matter
dark matter Modified gravity
2010/3/19
The premier alternative to the dark matter paradigm is modified gravity. Following an introduction to the relevant phenomenology of galaxies, I review the MOND paradigm, an effective summary of the ob...
