Testing General Relativity with Low-Frequency, Space-Based Gravitational-Wave Detectors

Jonathan R. Gair, Michele Vallisneri, Shane L. Larson +1

We review the tests of general relativity that will become possible with space-based gravitational-wave detectors operating in the ~0.01mHz - 1Hz low-frequency band. The fundamenta…

Prospects for probing strong gravity with a pulsar-black hole system

N. Wex, K. Liu, R. P. Eatough +3

The discovery of a pulsar (PSR) in orbit around a black hole (BH) is expected to provide a superb new probe of relativistic gravity and BH properties. Apart from a precise mass mea…

Extended gravity with generalized scalar field and kinetic term dependences

Tiberiu Harko, Francisco S. N. Lobo, Olivier Minazzoli

We generalize previous work by considering a novel gravitational model with an action given by an arbitrary function of the Ricci scalar, the matter Lagrangian density, a scalar fi…

Outlook for detection of GW inspirals by GRB-triggered searches in the Advanced detector era

Alexander Dietz, Nickolas Fotopoulos, Leo Singer +1

Short, hard gamma-ray bursts (GRBs) are believed to originate from the coalescence of two neutron stars (NSs) or a NS and a black hole (BH). If this scenario is correct, then short…

The classical mechanics of non-conservative systems

Chad R. Galley

Hamilton's principle of stationary action lies at the foundation of theoretical physics and is applied in many other disciplines from pure mathematics to economics. Despite its uti…

New derivation of the Lagrangian of a perfect fluid with a barotropic equation of state

Olivier Minazzoli, Tiberiu Harko

In this paper we give a simple proof that when the particle number is conserved, the Lagrangian of a barotropic perfect fluid is , where $ρ…

Searching for gravitational waves from binary coalescence

S. Babak, R. Biswas, P. R. Brady +25

We describe the implementation of a search for gravitational waves from compact binary coalescences in LIGO and Virgo data. This all-sky, all-time, multi-detector search for binary…

Testing general relativity with gravitational waves: a reality check

Michele Vallisneri

The observations of gravitational-wave signals from astrophysical sources such as binary inspirals will be used to test General Relativity for self consistency and against alternat…

Specialized Orthonormal Frames and Embedding

Frank B. Estabrook

We discuss some specializations of the frames of flat orthonormal frame bundles over geometries of indefinite signature, and the resulting symmetries of families of embedded Rieman…

Caustic echoes from a Schwarzschild black hole

Anıl Zenginoğlu, Chad R. Galley

We present the first numerical construction of the scalar Schwarzschild Green function in the time-domain, which reveals several universal features of wave propagation in black hol…

Towards beating the curse of dimensionality for gravitational waves using Reduced Basis

Frank Herrmann, Scott E. Field, Chad R. Galley +2

Using the Reduced Basis approach, we efficiently compress and accurately represent the space of waveforms for non-precessing binary black hole inspirals, which constitutes a four d…

Radiation reaction at 3.5 post-Newtonian order in effective field theory

Chad R. Galley, Adam K. Leibovich

We derive the radiation reaction forces on a compact binary inspiral through 3.5 order in the post-Newtonian expansion using the effective field theory approach. We utilize a recen…

Chameleon effect and the Pioneer anomaly

John D. Anderson, J. R. Morris

The possibility that the apparent anomalous acceleration of the Pioneer 10 and 11 spacecraft may be due, at least in part, to a chameleon field effect is examined. A small spacecra…

Support for the thermal origin of the Pioneer anomaly

Slava G. Turyshev, Viktor T. Toth, Gary Kinsella +3

We investigate the possibility that the anomalous acceleration of the Pioneer 10 and 11 spacecraft is due to the recoil force associated with an anisotropic emission of thermal rad…

Non-sky-averaged sensitivity curves for space-based gravitational-wave observatories

Michele Vallisneri, Chad R. Galley

(abridged) The signal-to-noise ratio (SNR) is used in gravitational-wave observations as the basic figure of merit for detection confidence and, together with the Fisher matrix, fo…
