SUMMARY:The Astrometric Effect of Gravitational Waves - Christopher Moore 
 (University of Cambridge)
DTSTART:20170127T130000Z
DTEND:20170127T140000Z
UID:TALK70732@talks.cam.ac.uk
CONTACT:Michalis Agathos
DESCRIPTION:A gravitational wave incident on the Earth causes the apparent
  positions of distant objects (e.g. stars!) to change periodically. The GA
 IA spacecraft is currently measuring the positions of a billion stars with
  accuracies down to several tens of microarcseconds. Therefore the finalis
 ed GAIA data release will offer a new opportunity to search for low freque
 ncy gravitational waves in the range (1.0e-8 - 3.0e-7) Hz. I will discuss 
 some of the challenges of searching for gravitational waves in large astro
 metric datasets\, and the sensitivity which can be achieved with the GAIA 
 dataset. I will also discuss the interesting effects that a gravitational 
 wave burst with memory can have on the apparent positions of distant objec
 ts.
