Detectability of Gravitational Waves from High-Redshift Binaries
Pablo A. Rosado, Paul D. Lasky, Eric Thrane +3
Recent non-detection of gravitational-wave backgrounds from pulsar timing arrays casts further uncertainty on the evolution of supermassive black hole binaries. We study the capabi…
Gravitational-wave cosmology across 29 decades in frequency
Paul D. Lasky, Chiara M. F. Mingarelli, Tristan L. Smith +24
Quantum fluctuations of the gravitational field in the early Universe, amplified by inflation, produce a primordial gravitational-wave background across a broad frequency band. We…
Versatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays
D. R. Madison, X. -J. Zhu, G. Hobbs +23
By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of…
The noise properties of 42 millisecond pulsars from the European Pulsar Timing Array and their impact on gravitational wave searches
R. N. Caballero, K. J. Lee, L. Lentati +36
The sensitivity of Pulsar Timing Arrays to gravitational waves depends on the noise present in the individual pulsar timing data. Noise may be either intrinsic or extrinsic to the…
European Pulsar Timing Array Limits on Continuous Gravitational Waves from Individual Supermassive Black Hole Binaries
Stanislav Babak, Antoine Petiteau, Alberto Sesana +33
We have searched for continuous gravitational wave (CGW) signals produced by individually resolvable, circular supermassive black hole binaries (SMBHBs) in the latest EPTA dataset,…
Limits on anisotropy in the nanohertz stochastic gravitational-wave background
S. R. Taylor, C. M. F. Mingarelli, J. R. Gair +32
The paucity of observed supermassive black hole binaries (SMBHBs) may imply that the gravitational wave background (GWB) from this population is anisotropic, rendering existing ana…
European Pulsar Timing Array Limits On An Isotropic Stochastic Gravitational-Wave Background
Lindley Lentati, Stephen R. Taylor, Chiara M. F. Mingarelli +33
We present new limits on an isotropic stochastic gravitational-wave background (GWB) using a six pulsar dataset spanning 18 yr of observations from the 2015 European Pulsar Timing…
Detection and localization of single-source gravitational waves with pulsar timing arrays
Xing-Jiang Zhu, Linqing Wen, George Hobbs +7
Pulsar timing arrays (PTAs) can be used to search for very low frequency (-- Hz) gravitational waves (GWs). In this paper we present a general method for the dete…
Expected properties of the first gravitational wave signal detected with pulsar timing arrays
Pablo A. Rosado, Alberto Sesana, Jonathan Gair
In this paper we attempt to investigate the nature of the first gravitational wave (GW) signal to be detected by pulsar timing arrays (PTAs): will it be an individual, resolved sup…
