Virgo!Results from Initial Detectors:Some highlights from LIGO and Virgo"Several ~year long science data runs by LIGO and VirgoSince 2007 all data analyzed jointly • Limits on GW emission from known msec pulsars – Crab pulsar emitting less than 2% of available spin-down energy ingravitational waves • Limits on compact binary (NS-NS, NS-BH, BH-BH) coalescence rates inour local neighborhood (~20 Mpc) • Limits on stochastic background in 100 Hz range – Limit beats the limit derived from Big Bang nucleosynthesis
1st GENERATIONDETECTORS 1 ST GENERATION INTERFEROMETERS CAN DETECT A NS-‐NS COALESCENCE AS FAR AS VIRGO CLUSTER (15 MPc) BUT THE EVENT RATE IS TOO LOW !! EXPECTED EVENT RATE: 0.01-‐0.1 ev/yr (NS-‐NS) FIRST DETECTION: POSSIBLE BUT UNLIKELY
