High-precision timing of 42 millisecond pulsars with the European Pulsar Timing Array

Understand

We report on the high-precision timing of 42 radio millisecond pulsars (MSPs) observed by the European Pulsar Timing Array (EPTA).

• This EPTA Data Release 1.0 extends up to mid-2014 and baselines range from 7-18 years.
• It forms the basis for the stochastic gravitational-wave background, anisotropic background, and continuous-wave limits recently presented by the EPTA elsewhere.
• The Bayesian timing analysis performed with TempoNest yields the detection of several new parameters: seven parallaxes, nine proper motions and, in the case of six binary pulsars, an apparent change of the semi-major axis.
