Self force via $m$-mode regularization and 2+1D evolution: II. Scalar-field implementation on Kerr spacetime
regularization 2+1D evolution Scalar-field implementation Kerr spacetime
2011/10/18
This is the second in a series of papers aimed at developing a practical time-domain method for self-force calculations in Kerr spacetime. The key elements of the method are (i) removal of a singular ...

Power-law holographic scalar field models dark energy PLECHDE model
2011/8/11
Abstract: In this work, the PLECHDE model with Granda-Oliveros infrared cutoff is studied and the evolution of dark energy density, deceleration and EoS parameters are calculated. I demonstrate that u...

Singular and non-singular endstates in massless scalar field collapse
2011/10/14
We study the collapse of a massless scalar field coupled to gravity. A class of blackhole solutions are identified. We also report on a class of solutions where collapse starts from a regular spacelik...
Distinguishability of scalar field models of dark energy with time variable equation of state parameter
cosmology dark energy–scalar field cosmic microwave background
2010/11/16
The possibility of distinguishing of scalar field models of dark energy with different Lagrangians and time variable equation of state parameter by available observational data is analyzed. The mul-ti...
Stability and QuasinormalModes of Black holes in Tensor-Vector-Scalar theory: Scalar Field Perturbations

The imminent detection of gravitational waves will trigger precision tests of gravity through
observations of quasinormal ringing of black holes. While General Relativity predicts just two po-larizat...
