... Optical observations of pulsars have been restricted to a small handful of objects which are probably not representative of the pulsar population. The main problem is that pulsars are optically faint with short radiative lives. The talk will review current Irish research in pulsars. ... The talk will conclude with a discussion of the implications for pulsar astronomy with the proposed ESO/EU 42 m optical telescope due to be commissioned 2017. ... Last Revised: 2007 January 31st . ...
Pulsars are great probes for exploring theories of gravitation and detection of gravitational waves. Observations of binary pulsar systems, particularly the Double Pulsar system, have provided the most stringent tests of relativistic gravity in strong-field situations, confirming the accuracy of EinsteinТЙs general theory of relativity. Pulsar Timing Arrays (PTAs) have as a main aim the detection and study of nanohertz gravitational waves (GWs). ...
