EPTA pulsars

The EPTA collaboration has categorised 18 pulsars as 'Priority 1', meaning that they offer the highest timing precision using our telescopes. They are the most promising candidates for gravitational wave detection, and accurate timing of some of these pulsars will also allow us to make improved studies of the pulsar systems themselves. The Priority 1 pulsars form the backbone of the array because they have already shown excellent timing precision and are, in most cases, visible to all five EPTA telescopes. Many more pulsars than these are observed as part of the EPTA timing programme, assisting with gravitational wave detection and other research objectives.
