Pulsars are rotating magnetized neutron stars, emitting pulses of radiation at regular intervals. These pulse timings are measured extremely accurately, to the level of one part in 10^15. This remarkable accuracy was used for the first indirect detection of gravitational waves. We discuss how pulsars can act as resonant Weber detectors of gravitational waves (GW), whose signals can be monitored on earth in terms of the perturbation of the regular pulses coming from the pulsar. These pulsars, thus, can provide us a family of remotely stationed detectors all of which can be monitored on earth. As any GW reaching earth directly also travels to pulsars, the affected pulsar signal necessarily will reach earth on a later date which can be accurately predicted from known locations of the pulsars and GW sources. This leads to a very exciting possibility of detecting those GW events whose direct signals reached earth in past, hence were missed, such as from past supernova events. We give a list of GW sources (e.g. earliest known supernova SN185 recorded in AD 185) and pulsars which will carry the respective GW signals to earth on specific dates in future. |
