A nonlinear scalar model of extreme mass ratio inspirals in effective field theory I. Self force through third order

Chad R. Galley

The motion of a small compact object in a background spacetime is investigated in the context of a model nonlinear scalar field theory. This model is constructed to have a perturba…

Multibaseline gravitational wave radiometry

Dipongkar Talukder, Sanjit Mitra, Sukanta Bose

We present a statistic for the detection of stochastic gravitational wave backgrounds (SGWBs) using radiometry with a network of multiple baselines. We also quantitatively compare…

LISA Sensitivities to Gravitational Waves from Relativistic Metric Theories of Gravity

Massimo Tinto, Márcio Eduardo da Silva Alves

The direct observation of gravitational waves will provide a unique tool for probing the dynamical properties of highly compact astrophysical objects, mapping ultra-relativistic re…

Conservative corrections to the innermost stable circular orbit (ISCO) of a Kerr black hole: a new gauge-invariant post-Newtonian ISCO condition, and the ISCO shift due to test-particle spin and the gravitational self-force

Marc Favata

The innermost stable circular orbit (ISCO) delimits the transition from circular orbits to those that plunge into a black hole. In the test-mass limit, well-defined ISCO conditions…

Matter-wave Tests of the Gravitational Redshift in Space

Holger Mueller, Michael A. Hohensee, Nan Yu

A recent measurement of the gravitational redshift was based on interference of matter waves. Operation in microgravity can improve it by a factor of and, in some models, ev…

Conservative self-force correction to the innermost stable circular orbit: comparison with multiple post-Newtonian-based methods

Marc Favata

[abridged] Barack & Sago have recently computed the shift of the innermost stable circular orbit (ISCO) due to the conservative self-force that arises from the finite-mass of an or…

Gravitational wave detection with single-laser atom interferometers

Nan Yu, Massimo Tinto

We present a new general design approach of a broad-band detector of gravitational radiation that relies on two atom interferometers separated by a distance L. In this scheme, only…

Advancing Tests of Relativistic Gravity via Laser Ranging to Phobos

Slava G. Turyshev, William Farr, William M. Folkner +5

Phobos Laser Ranging (PLR) is a concept for a space mission designed to advance tests of relativistic gravity in the solar system. PLR's primary objective is to measure the curvatu…

Searches for Cosmic-String Gravitational-Wave Bursts in Mock LISA Data

Michael I. Cohen, Curt Cutler, Michele Vallisneri

A network of observable, macroscopic cosmic (super-)strings may have formed in the early universe. If so, the cusps that generically develop on cosmic-string loops emit bursts of g…

The Mock LISA Data Challenges: from Challenge 3 to Challenge 4

Stanislav Babak, John G. Baker, Matthew J. Benacquista +27

The Mock LISA Data Challenges are a program to demonstrate LISA data-analysis capabilities and to encourage their development. Each round of challenges consists of one or more data…

The Pioneer Anomaly

Slava G. Turyshev, Viktor T. Toth

Radio-metric Doppler tracking data received from the Pioneer 10 and 11 spacecraft from heliocentric distances of 20-70 AU has consistently indicated the presence of a small, anomal…
