TO TRIGGER OR TO BE TRIGGERED: THE TWO FACES OF THE PULSAR TIMING ARRAYS IN THE MULTIMESSENGER CONTEXT
The rotational stability of a subset of the “recycled” pulsars opens the possibility to exploit them as components of a galactic scale gravitational wave detector, known as Pulsar Timing Array (PTA), in turn providing a unique instrument to search for gravitational waves (GWs) in the ultra-long period range, nicely complementary to the frequency range of other current or future GW detectors. The PTA experiments have recently published intriguing results, showing the first evidences for a detection, yet to be supported by additional data and analysis. In this contribution it will be discussed how the PTAs can benefit of multi-messenger programs or will be able to trigger multi-messenger follow-ups with a special focus for the European Pulsar Timing Array (EPTA) case.
