A physical template family for gravitational waves from precessing binaries of spinning compact objects: Application to single-spin binaries

Yi Pan, Alessandra Buonanno, Yanbei Chen +1

The detection of the gravitational waves (GWs) emitted by precessing binaries of spinning compact objects is complicated by the large number of parameters (such as the magnitudes a…

Time Delay Interferometry with Moving Spacecraft Arrays

Massimo Tinto, Frank B. Estabrook, adn J. W. Armstrong

Space-borne interferometric gravitational wave detectors, sensitive in the low-frequency (millihertz) band, will fly in the next decade. In these detectors the spacecraft-to-spacec…

Noise characterization for LISA

Julien Sylvestre, Massimo Tinto

We consider the general problem of estimating the inflight LISA noise power spectra and cross-spectra, which are needed for detecting and estimating the gravitational wave signals…

Analysis of LIGO data for gravitational waves from binary neutron stars

The LIGO Scientific Collaboration, B. Abbott

We report on a search for gravitational waves from coalescing compact binary systems in the Milky Way and the Magellanic Clouds. The analysis uses data taken by two of the three LI…

SyZyGy: A Straight Interferometric Spacecraft System for Gravity Wave Observations

F. B. Estabrook, J. W. Armstrong, Massimo Tinto +1

We apply TDI, unfolding the general triangular configuration, to the special case of a linear array of three spacecraft. We show that such an array ("SyZyGy") has, compared with an…

Data Combinations Accounting for LISA Spacecraft Motion

Daniel A. Shaddock, Massimo Tinto, Frank B. Estabrook +1

LISA is an array of three spacecraft in an approximately equilateral triangle configuration which will be used as a low-frequency gravitational wave detector. We present here new g…

Pioneer Anomaly and the Helicity-Rotation Coupling

John D. Anderson, Bahram Mashhoon

The modification of the Doppler effect due to the coupling of the helicity of the radiation with the rotation of the source/receiver is considered in the case of the Pioneer 10/11…

Operating LISA as a Sagnac interferometer

Daniel A. Shaddock

A phase-locking configuration for LISA is proposed that provides a significantly simpler mode of operation. The scheme provides one Sagnac signal readout inherently insensitive to…

Gravitational decoherence

Pieter Kok, Ulvi Yurtsever

We investigate the effect of quantum metric fluctuations on qubits that are gravitationally coupled to a background spacetime. In our first example, we study the propagation of a q…

Study of an electro-optic modulator capable of generating simultaneous amplitude and phase modulations

Benedict J Cusack, Benjamin S Sheard, Daniel A Shaddock +3

We report on the analysis and prototype-characterization of a dual-electrode electro-optic modulator that can generate both amplitude and phase modulations with a selectable relati…

On the Circular Orbit Approximation for Binary Compact Objects In General Relativity

Mark Miller

One often-used approximation in the study of binary compact objects (i.e., black holes and neutron stars) in general relativity is the instantaneously circular orbit assumption. Th…

The Holographic Entropy Bound and Local Quantum Field Theory

Ulvi Yurtsever

The maximum entropy that can be stored in a bounded region of space is in dispute: it goes as volume, implies (non-gravitational) microphysics; it goes as the surface area, asserts…

Implementation of Time-Delay Interferometry for LISA

Massimo Tinto, Daniel A. Shaddock, Julien Sylvestre +1

We discuss the baseline optical configuration for the Laser Interferometer Space Antenna (LISA) mission, in which the lasers are not free-running, but rather one of them is used as…

Head-on/Near Head-on Collisions of Neutron Stars With a Realistic EOS

Edwin Evans, A. Gopakumar, Philip Gressman +4

It has been conjectured that in head-on collisions of neutron stars (NSs), the merged object would not collapse promptly even if the total mass is higher than the maximum stable ma…
