GWADW Elba Since Kyoto 2010 … S6/VSR3, with alerts to telescopes/SWIFT S6/VSR3, with alerts to telescopes/SWIFT –Capability of almost real time data analysis –Detector data quality assessment –Sufficiently low transient rate in detectors Big Dog blind injection challenge Big Dog blind injection challenge –In vivo review of detection procedures –Built much higher confidence in the detection process aLIGO started work on sites aLIGO started work on sites –Impressive plan to be back with a working interferometer within a few years LCGT approved LCGT approved –hope that the difficulties from the earthquake/tsunami will be overcome, ready to support AdVirgo will start work this fall: AdVirgo will start work this fall: –Joint GEO-HF Virgo run –Then AdV oriented tests GEO-HF with squeezing is there GEO-HF with squeezing is there

GWADW Elba An example from space: after many efforts First few minutes of AMS (Very preliminary and uncalibrated)

GWADW Elba Environmental noise, gravity fluctuations Hopefully soon we’ll arrive to Newtonian noise Hopefully soon we’ll arrive to Newtonian noise –Underground –Seismic correction Accelerometers, tiltmeters Accelerometers, tiltmeters Long time scale effects in materials Long time scale effects in materials

GWADW Elba Thermal noise Mirror thermal noise sets the noise floor in future interferometers Mirror thermal noise sets the noise floor in future interferometers Not yet in current km scale ones Not yet in current km scale ones Progress? Progress? –Reduction of mass of mechanically bad material –Can there be new materials or processes that can improve thermal noise?
