Parkes Pulsar Timing Array constraints on ultralight scalar-field dark matter
Nataliya K. Porayko, Xingjiang Zhu, Yuri Levin +27
It is widely accepted that dark matter contributes about a quarter of the critical mass-energy density in our Universe. The nature of dark matter is currently unknown, with the mas…
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…
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,…
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…
Targeting supermassive black hole binaries and gravitational wave sources for the pulsar timing array
Pablo A. Rosado, Alberto Sesana
This paper presents a technique to search for supermassive black hole binaries (MBHBs) in the Sloan Digital Sky Survey (SDSS). The search is based on the peculiar properties of mer…
