  1. 26. A summary of seismic data analyses at the ET candidate site in Sardinia (Italy)

    Talk

    Almost ten years after the first seismic measurements at the Sos Enattos mine, the characterization of the seismic noise wavefield at the ET candidate site in Sardinia has progressed considerably. In this talk, I present a summary of the main results from the active and passive seismic surveys conducted thus far. Particular emphasis is put on those parameters which are most relevant to the...

    Talk

    Gravitational-wave detectors are very sensitive instruments that suffer from a huge number of noises. If we aim to observe gravitational waves with Earth-based detectors, we need to take care of every source that can prevent that observation.
    Seismic noise is a huge problem in the low frequency band and it is tackled with suspensions and active controls. The low frequency band can also be...

    Talk

    In this talk I summarize the principal aspects to be considered for broadband seismometer deployment in boreholes, which are useful sensing devices for a Newtonian Noise subtraction system. I show what we learned from this kind of installations in Sardinia, e.g. costs and technical aspects to be considered. Finally, I point out some considerations about the development of seismometer chains...

  7. 36. Bayesian ML algorithm for array optimization
    Francesca Badaracco (GSSI)
    10/11/2021, 12:00
    Talk

    Newtonian noise (NN) will be the very last sensitivity wall in GW detectors below 10-30 Hz. A NN cancellation system is already foreseen in Virgo for O4. For cancelling this noise, we need arrays of seismic sensors deployed in an optimal way close to the test masses. However, when the seismic field deviates from homogeneity and isotropy, finding the optimal array becomes very challenging. An...
