9 LSC-VIRGO -VSR1 Analysis VSR1 Network

10 LSC-VIRGO -VSR1 Analysis Link to P.Shawnan Review http://sites.google.com/site/amaldiproject8tuesday623/presentations-1 VSR1 Network

11 LSC-VIRGO -VSR1 Analysis Continuous Waves CRAB - No more than 4–6% of the spin-down energy is going into GW emission VELA – Results under review

12 < 3.6 per year Bursts Placed limit on GW energy spectral density:  0 < 6.5 × 10 –5 Stochastic

13 Coalescing Binaries GRB 070201 –Short, hard gamma-ray burst –Consistent with being in M31 –Leading model for short GRBs: binary merger involving a neutron star –Searched for both inspiral and burst signals –No plausible GW signal found
