EPTA & LEAP: Using pulsars to detect gravitational waves |
High precision timing of an array of millisecond pulsars is sensitive to a stochastic background of gravitational waves with frequencies in the nano-Hertz regime. The gravitational waves in this frequency range are thought to be generated by a large number of merging blackholes in the early universe and/or relic gravitational waves like those from cosmic strings. I will discuss the European Pulsar Timing Array, one of three projects around the world working to directly detect these gravitational waves. Our present best limit on a stochastic background will be presented. I will also discuss the Large European Array for Pulsars project which will use five European telescopes in a coherent mode to form the a large steeerable telescope. LEAP has an excellent chance of making the first direct detection in the nanoHz range. |
