The NANOGrav 11-Year Data Set: Limits on Gravitational Wave Memory
K. Aggarwal, Z. Arzoumanian, P. T. Baker +58
The mergers of supermassive black hole binaries (SMBHBs) promise to be incredible sources of gravitational waves (GWs). While the oscillatory part of the merger gravitational wavef…
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…
NANOGrav Education and Outreach: Growing a Diverse and Inclusive Collaboration for Low-Frequency Gravitational Wave Astronomy
The NANOGrav Collaboration, P. T. Baker, H. Blumer +25
The new field of gravitational wave astrophysics requires a growing pool of students and researchers with unique, interdisciplinary skill sets. It also offers an opportunity to bui…
Catching Gravitational Waves With A Galaxy-sized Net Of Pulsars
Stephen R. Taylor
Until recently, the only way to observe the Universe was from light received by telescopes. But we are now able to measure gravitational waves, which are ripples in the fabric of t…
Bayesian cross validation for gravitational-wave searches in pulsar-timing array data
Haochen Wang, Stephen R. Taylor, Michele Vallisneri
Gravitational-wave data analysis demands sophisticated statistical noise models in a bid to extract highly obscured signals from data. In Bayesian model comparison, we choose among…
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…
Supermassive Black-hole Demographics & Environments With Pulsar Timing Arrays
Stephen R. Taylor, Sarah Burke-Spolaor, Paul T. Baker +6
Precision timing of large arrays (>50) of millisecond pulsars will detect the nanohertz gravitational-wave emission from supermassive binary black holes within the next ~3-7 years.…
