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

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

Coalescing Binaries GRB –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
