European Pulsar Timing Array Limits On An Isotropic Stochastic Gravitational-Wave Background
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 Array data release.Expand

The International Pulsar Timing Array: First Data Release
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 milliseconds can beExpand

High-precision timing of 42 millisecond pulsars with the European Pulsar Timing Array
We report on timing, flux density, and polarimetric observations of the transient magnetar and 5.54 s radio pulsar XTE J1810-197 using the GBT, Nancay, and Parkes radio telescopes beginning in earlyExpand

European Pulsar Timing Array Limits on Continuous Gravitational Waves from Individual Supermassive Black Hole Binaries
We have searched for continuous gravitational wave (CGW) signals produced by individually resolvable, circular supermassive black hole binaries (SMBHBs) in the latest European Pulsar Timing ArrayExpand

Blocking low-eccentricity EMRIs: a statistical direct-summation N-body study of the Schwarzschild barrier
ABSTRACT 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 aroundit. Recent work onExpand

All correlations must die: Assessing the significance of a stochastic gravitational-wave background in pulsar timing arrays
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 quadrupolarExpand

From spin noise to systematics: Stochastic processes in the first International Pulsar Timing Array data release
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 selection toExpand

Limits on Anisotropy in the Nanohertz Stochastic Gravitational Wave Background.
The paucity of observed supermassive black hole binaries (SMBHBs) may imply that the gravitational wave background (GWB) from this population is anisotropic, rendering existing analyses suboptimal.Expand

Mergers of multimetallic globular clusters: the role of dynamics
Hubble Space Telescope observations of globular clusters (GCs) in the Antenn galaxy show clusters of clusters, or regions in the galaxy that span hundreds of parsecs, where many of the GCs are doomedExpand

THE BUTTERFLY EFFECT IN THE EXTREME-MASS RATIO INSPIRAL PROBLEM
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 massive black hole (MBH)Expand
