Comparison between numerical relativity and a new class of post-Newtonian gravitational-wave phase evolutions: the non-spinning equal-mass case
Achamveedu Gopakumar, Mark Hannam, Sascha Husa +1
We compare the phase evolution of equal-mass nonspinning black-hole binaries from numerical relativity (NR) simulations with post-Newtonian (PN) results obtained from three PN appr…
The cross-correlation search for periodic gravitational waves
Sanjeev Dhurandhar, Badri Krishnan, Himan Mukhopadhyay +1
In this paper we study the use of cross-correlations between multiple gravitational wave (GW) data streams for detecting long-lived periodic signals. Cross-correlation searches bet…
Hyperboloidal foliations and scri-fixing
Anıl Zenginoğlu
We discuss a gauge choice which allows us to avoid the introduction of artificial timelike outer boundaries in numerical studies of test fields based on a 3+1 decomposition of asym…
Comparison between numerical-relativity and post-Newtonian waveforms from spinning binaries: the orbital hang-up case
Mark Hannam, Sascha Husa, Bernd Brügmann +1
We compare results from numerical simulations of spinning binaries in the "orbital hangup" case, where the binary completes at least nine orbits before merger, with post-Newtonian…
Phase and alignment noise in grating interferometers
A. Freise, A. Bunkowski, R. Schnabel
Diffraction gratings have been proposed as core optical elements in future laser-interferometric gravitational-wave detectors. In this paper we derive equations for the coupling be…
Verifying black hole orbits with gravitational spectroscopy
Steve Drasco
Gravitational waves from test masses bound to geodesic orbits of rotating black holes are simulated, using Teukolsky's black hole perturbation formalism, for about ten thousand gen…
The influence of the hydrodynamic drag from an accretion torus on extreme mass-ratio inspirals
E. Barausse, L. Rezzolla
We have studied extreme mass-ratio inspirals (EMRIs) in spacetimes containing a rotating black hole and a non self-gravitating torus with constant specific angular momentum. We hav…
Conformal classes of asymptotically flat, static vacuum data
Helmut Friedrich
We show that time-reflection symmetric, asymptotically flat, static vacuum data which admit a non-trivial conformal rescaling which leads again to such data must be axi-symmetric a…
Summary of GR18 Numerical Relativity parallel sessions (B1/B2 and B2), Sydney, 8-13 July 2007
Carsten Gundlach
The numerical relativity session at GR18 was dominated by physics results on binary black hole mergers. Several groups can now simulate these from a time when the post-Newtonian eq…
Time-frequency analysis of extreme-mass-ratio inspiral signals in mock LISA data
Jonathan R Gair, Ilya Mandel, Linqing Wen
Extreme-mass-ratio inspirals (EMRIs) of ~ 1-10 solar-mass compact objects into ~ million solar-mass massive black holes can serve as excellent probes of strong-field general relati…
Photon pressure induced test mass deformation in gravitational-wave detectors
S. Hild, M. Brinkmann, K. Danzmann +14
A widely used assumption within the gravitational-wave community has so far been that a test mass acts like a rigid body for frequencies in the detection band, i.e. for frequencies…
Using generalized PowerFlux methods to estimate the parameters of periodic gravitational waves
Gregory Mendell, Karl Wette
We investigate methods to estimate the parameters of the gravitational-wave signal from a spinning neutron star using Fourier transformed segments of the strain response from an in…
Finite Mirror Effects in Advanced Interferometric Gravitational Wave Detectors
Andrew P. Lundgren, Ruxandra Bondarescu, David Tsang +1
Thermal noise is expected to be the dominant source of noise in the most sensitive frequency band of second generation ground based gravitational wave detectors. Reshaping the beam…
A template bank for gravitational waveforms from coalescing binary black holes: non-spinning binaries
P. Ajith, S. Babak, Y. Chen +15
Gravitational waveforms from the inspiral and ring-down stages of the binary black hole coalescences can be modelled accurately by approximation/perturbation techniques in general…
Sub-leading contributions to the black hole entropy in the brick wall approach
Sudipta Sarkar, S. Shankaranarayanan, L. Sriramkumar
[Abridged] We compute the canonical entropy of a quantum scalar field around static and spherically symmetric black holes through the brick wall approach at the higher orders (in f…
Near-Constant Mean Curvature Solutions of the Einstein Constraint Equations with Non-Negative Yamabe Metrics
James Isenberg, Adam Clausen, Paul T Allen
We show that sets of conformal data on closed manifolds with the metric in the positive or zero Yamabe class, and with the gradient of the mean curvature function sufficiently smal…
On the mechanical quality factors of cryogenic test masses from fused silica and crystalline quartz
Anja Schroeter, Ronny Nawrodt, Roman Schnabel +11
Current interferometric gravitational wave detectors (IGWDs) are operated at room temperature with test masses made from fused silica. Fused silica shows very low absorption at the…
The plane symmetric Einstein-dust system with positive cosmological constant
S. B. Tchapnda
The Einstein equations with a positive cosmological constant are coupled to the pressureless perfect fluid matter in plane symmetry. Under suitable restrictions on the initial data…
Thermal diagnostic of the Optical Window on board LISA Pathfinder
M. Nofrarias, A. F. Garcia Marin, A. Lobo +4
Vacuum conditions inside the LTP Gravitational Reference Sensor must comply with rather demanding requirements. The Optical Window (OW) is an interface which seals the vacuum enclo…
Best network chirplet-chain: Near-optimal coherent detection of unmodeled gravitation wave chirps with a network of detectors
Archana Pai, Eric Chassande-Mottin, Olivier Rabaste
The searches of impulsive gravitational waves (GW) in the data of the ground-based interferometers focus essentially on two types of waveforms: short unmodeled bursts and chirps fr…
