Abstract The first direct detection of gravitational waves may be made through observations of pulsars. The principal aim of pulsar timing-array projects being carried out worldwide is to detect ultra-low frequency gravitational waves (f ∼ 10−9–10−8 Hz). Such waves are expected to be caused by coalescing supermassive binary black holes in the cores of merged galaxies. It is also possible that a detectable signal could have been produced in the inflationary era or by cosmic strings. In this…

Status update of the Parkes pulsar timing array

The Parkes Pulsar Timing Array project aims to make a direct detection of a gravitational wave background through the timing of millisecond pulsars. In this paper, the main requirements for that

Gravitational Wave Detection by Interferometry (Ground and Space)

The main theme of this review is a discussion of the mechanical and optical principles used in the various long baseline systems in operation around the world — LIGO, Virgo, TAMA300 and LCGT, and GEO600 — and in LISA, a proposed space-borne interferometer.
