How to Detect an Astrophysical Nanohertz Gravitational-Wave Background
Bence Bécsy, Neil J. Cornish, Patrick M. Meyers +93
Analysis of pulsar timing data have provided evidence for a stochastic gravitational wave background in the nHz frequency band. The most plausible source of such a background is th…
The NANOGrav 12.5-year Data Set: Search for Gravitational Wave Memory
Gabriella Agazie, Zaven Arzoumanian, Paul T. Baker +87
We present the results of a Bayesian search for gravitational wave (GW) memory in the NANOGrav 12.5-yr data set. We find no convincing evidence for any gravitational wave memory si…
Efficient large-scale, targeted gravitational-wave probes of supermassive black-hole binaries
Maria Charisi, Stephen R. Taylor, Caitlin A. Witt +1
Supermassive black hole binaries are promising sources of low-frequency gravitational waves (GWs) and bright electromagnetic emission. Pulsar timing array searches for resolved bin…
Searching for continuous Gravitational Waves in the second data release of the International Pulsar Timing Array
M. Falxa, S. Babak, P. T. Baker +123
The International Pulsar Timing Array 2nd data release is the combination of datasets from worldwide collaborations. In this study, we search for continuous waves: gravitational wa…
A Parallelized Bayesian Approach To Accelerated Gravitational-Wave Background Characterization
Stephen R. Taylor, Joseph Simon, Levi Schult +2
The characterization of nanohertz-frequency gravitational waves (GWs) with pulsar-timing arrays requires a continual expansion of datasets and monitored pulsars. Whereas detection…
The NANOGrav 12.5-year data set: Search for Non-Einsteinian Polarization Modes in theGravitational-Wave Background
Zaven Arzoumanian, Paul T. Baker, Harsha Blumer +68
We search NANOGrav's 12.5-year data set for evidence of a gravitational wave background (GWB) with all the spatial correlations allowed by general metric theories of gravity. We fi…
Discriminating between different scenarios for the formation and evolution of massive black holes with LISA
Alexandre Toubiana, Kaze W. K. Wong, Stanislav Babak +5
Electromagnetic observations have provided strong evidence for the existence of massive black holes in the center of galaxies, but their origin is still poorly known. Different sce…
Pulsar timing array signals induced by black hole binaries in relativistic eccentric orbits
Abhimanyu Susobhanan, Achamveedu Gopakumar, George Hobbs +1
Individual supermassive black hole binaries in non-circular orbits are possible nanohertz gravitational wave sources for the rapidly maturing Pulsar Timing Array experiments. We de…
Understanding in Gravitational Wave Experiments
Chiara M. F. Mingarelli, Stephen R. Taylor, B. S. Sathyaprakash +1
In this paper we provide a comprehensive derivation of the energy density in the stochastic gravitational-wave background , and show how this quantity is measured…
Constraining alternative polarization states of gravitational waves from individual black hole binaries using pulsar timing arrays
Logan O'Beirne, Neil J. Cornish, Sarah J. Vigeland +1
Pulsar timing arrays are sensitive to gravitational wave perturbations produced by individual supermassive black hole binaries during their early inspiral phase. Modified gravity t…

Neil J. Cornish, Logan O'Beirne, Stephen R. Taylor +1
The opening of the gravitational wave window by ground-based laser interferometers has made possible many new tests of gravity, including the first constraints on polarization. It…
