## Abstract

The European Pulsar Timing Array (EPTA) network is a collaboration between the five largest radio telescopes in Europe aiming to study the astrophysics of millisecond pulsars and to detect cosmological gravitational waves in the nano-Hertz regime. The advantages and techniques of handling the multi-telescope datasets of a number of sources will be presented. In addition, the results of the EPTA timing analysis of the pulsar-white dwarf binary PSR J1012+5307 will be reported. Specifically, the measurements for the first time for this system, of the parallax, the variation of the projected semi-major axis and of the orbital period. Finally, the derived stringent, theory independent limits on alternative theories of gravity, with the use of this ideal laboratory for strong- field gravity tests, will be presented.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
