Search for gravitational wave ringdowns from perturbed black holes in LIGO S4 data
The LIGO Scientific Collaboration, B. Abbott
According to general relativity a perturbed black hole will settle to a stationary configuration by the emission of gravitational radiation. Such a perturbation will occur, for exa…
Stationary hyperboloidal slicings with evolved gauge conditions
Frank Ohme, Mark Hannam, Sascha Husa +1
We analyze stationary slicings of the Schwarzschild spacetime defined by members of the Bona-Masso family of slicing conditions. Our main focus is on the influence of a non-vanishi…
Search for Gravitational Waves from Low Mass Binary Coalescences in the First Year of LIGO's S5 Data
LIGO Scientific Collaboration, B. Abbott
We have searched for gravitational waves from coalescing low mass compact binary systems with a total mass between 2 and 35 Msun and a minimum component mass of 1 Msun using data f…
Towards a gauge-polyvalent Numerical Relativity code
Daniela Alic, Carles Bona, Carles Bona-Casas
The gauge polyvalence of a new numerical code is tested, both in harmonic-coordinate simulations (gauge-waves testbed) and in singularity-avoiding coordinates (simple Black-Hole si…
Gravitational perturbations of Schwarzschild spacetime at null infinity and the hyperboloidal initial value problem
Anil Zenginoglu, Dario Nunez, Sascha Husa
We study gravitational perturbations of Schwarzschild spacetime by solving a hyperboloidal initial value problem for the Bardeen-Press equation. Compactification along hyperboloida…
Flat deformation theorem and symmetries in spacetime
Josep Llosa, Jaume Carot
The \emph{flat deformation theorem} states that given a semi-Riemannian analytic metric on a manifold, locally there always exists a two-form , a scalar function , and an…
