The Cagliari pulsar group is part of the Cagliari Astronomical Observatory. We study many aspects of pulsar astronomy including pulsar timing, its use to detect gravitational waves, the origin and evolution of pulsars, pulsar emission properties and mechanisms and the connection between radio pulsars and other neutron stars - in particular the mysterious Fast Radio Bursts - and their environments.

In the last decades we have actively participated in all major pulsar search experiments using the Parkes radio telescope and, more recently, the MeerKAT telescope: in the Parkes High-latitude survey we found the first double pulsar system J0737-3039A/B (Burgay et al. 2003, Nature; Lyne et al. 2004, Science) and through the High Time Resolution Universe Survey, the astrophysical nature of Fast Radio Burst was finally assessed. Searches with MeerKAT led to many exciting discoveries, including a pulsar with a massive companion, either the heaviest Neutron Star or the lightest Black Hole!

As part of the European Pulsar Timing Array collaboration (EPTA) we are participating to the International Pulsar Timing Array, aimed at detecting and studying gravitational waves in the nenoHertz regime. EPTA received the Royal Astronomical Society Group Achievement Award 2025 for its ground breaking results.
