All correlations must die: Assessing the significance of a stochastic gravitational-wave background in pulsar-timing arrays
S. R. Taylor, L. Lentati, S. Babak +4
We present two methods for determining the significance of a stochastic gravitational-wave (GW) background affecting a pulsar-timing array, where detection is based on evidence for…
From Spin Noise to Systematics: Stochastic Processes in the First International Pulsar Timing Array Data Release
L. Lentati, R. M. Shannon, W. A. Coles +80
We analyse the stochastic properties of the 49 pulsars that comprise the first International Pulsar Timing Array (IPTA) data release. We use Bayesian methodology, performing model…
The International Pulsar Timing Array: First Data Release
J. P. W. Verbiest, L. Lentati, G. Hobbs +89
The highly stable spin of neutron stars can be exploited for a variety of (astro-)physical investigations. In particular arrays of pulsars with rotational periods of the order of m…
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…
Tidal disruptions in circumbinary disks. II: Observational signatures in the reverberation spectra
Patrick Brem, Jorge Cuadra, Pau Amaro-Seoane +1
Supermassive Binary Black Holes (SMBBHs) with sub-pc separations form in the course of galaxy mergers, if both galaxies harbour massive black holes. Clear observational evidence fo…
Relativistic mergers of compact binaries in clusters: The fingerprint of the spin
Patrick Brem, Pau Amaro-Seoane, Rainer Spurzem
Dense stellar systems such as globular clusters and dense nuclear clusters are the breeding ground of sources of gravitational waves for the advanced detectors LIGO and Virgo. Thes…
Tidal disruptions in circumbinary discs (I): Star formation, dynamics, and binary evolution
Pau Amaro-Seoane, Patrick Brem, Jorge Cuadra
In our current interpretation of the hierarchical structure of the universe it is well established that galaxies collide and merge with each other during their lifetime. If massive…
Blocking low-eccentricity EMRIs: A statistical direct-summation N-body study of the Schwarzschild barrier
Patrick Brem, Pau Amaro-Seoane, Carlos F. Sopuerta
The capture of a compact object in a galactic nucleus by a massive black hole (MBH), an extreme-mass ratio inspiral (EMRI), is the best way to map space and time around it. Recent…
Fake plunges are very eccentric real EMRIs in disguise ... they dominate the rates and are blissfully ignorant of angular momentum barriers
Pau Amaro-Seoane, Carlos Sopuerta, Patrick Brem
The capture of a compact object in a galactic nucleus by a massive black hole (MBH) is the best way to map space and time around it. Compact objects such as stellar black holes on…
The butterfly effect in the extreme-mass ratio inspiral problem
Pau Amaro-Seoane, Patrick Brem, Jorge Cuadra +1
Measurements of gravitational waves from the inspiral of a stellar-mass compact object into a massive black hole are unique probes to test General Relativity (GR) and MBH propertie…
Mergers of multi-metallic globular clusters: The role of dynamics
Pau Amaro-Seoane, Symeon Konstantinidis, Patrick Brem +1
Hubble Space Telescope observations of globular clusters (GCs) in the Antennae galaxy show clusters of clusters, or regions in the galaxy that span hundreds of parsecs, where many…
