Addressing the spin question in gravitational-wave searches: Waveform templates for inspiralling compact binaries with nonprecessing spins
Addressing spin question gravitational-wave searches Waveform templates inspiralling
2011/10/18
This paper presents a post-Newtonian (PN) template family of gravitational waveforms from inspiralling compact binaries with non-precessing spins, where the spin effects are described by a single "red...
Genericity of black holes and naked singularities in gravitational collapse
Gravitational collapse black holes naked singularity
2011/10/14
We investigate here the genericity and stability aspects for naked singularities and black holes that arise as the final states for a complete gravitational collapse of a spherical massive matter clou...
Black hole perturbation in parity violating gravitational theories
Black hole perturbation parity violating gravitational theories
2011/10/14
We study linear perturbations around the static and spherically symmetric spacetime for the gravitational theories whose Lagrangian depends on Ricci scalar and the parity violating Chern-Simons term. ...

Structure, Deformations Gravitational Wave Emission of Magnetars
2010/11/15
Neutron stars can have, in some phases of their life, extremely strong magnetic fields, up to 1015−16 G. These objects, named magnetars, could be powerful sources of gravitational waves, since t...
Dynamics of Viscous Dissipative Plane Symmetric Gravitational Collapse
Gravitational collapse Dissipation Junction conditions Dynamical equations Transport equations
2010/3/18
We present dynamical description of gravitational collapse in view of Misner and Sharp's formalism. Matter under consideration is a complicated fluid consistent with plane symmetry which we assume to ...
Effects of the Electromagnetic Field on Five-dimensional Gravitational Collapse
Electromagnetic field Gravitational collapse Cosmological constant
2010/3/18
This paper investigates the five-dimensional(5D) spherically symmetric gravitational collapse with positive cosmological constant in the presence of an electromagnetic field. The junction conditions b...
