Ppta3

The Third ATNF Gravitational Wave Workshop

Date: 11th Dec 2009
Place: ATNF Lecture Theatre, Marsfield, Sydney
Organisers: George Hobbs & Dick Manchester
Aim: To highlight results from the Parkes Pulsar Timing Array (PPTA) project, to discuss astrophysical sources of gravitational waves and to discuss future issues
Registration: Please contact George Hobbs if you wish to participate as a speaker and present a talk or as part of the audience.

Background information

Data have been collected for the Parkes Pulsar Timing Array (PPTA) project over the past 4 years. The main goal of the PPTA project is to make the first direct detection of gravitational waves. Already, we have used our data to limit the existence of a stochastic background of low-frequency gravitational waves. Other results from the project have included constraining Solar system planetary masses, studying the Solar corona and probing the interstellar medium. In the near future we expect to limit the existence of single coalescing massive black-hole binary systems to high red-shift, place limits on various theories of gravity, study pulsar spin-down and search for irregularities in terrestrial time standards.
