Effects of near-surface sedimentary structure on Newtonian noise for the Einstein Telescope: a 2-D numerical study
Shi Yao, Patrick Schillings, Johannes Erdmann +1
Near-surface low-velocity sediments can strongly modify seismic wavefields and therefore affect estimates of Newtonian noise at underground gravitational-wave observatories. We inv…
Optimization and robustness of cost-efficient seismic arrays for Newtonian noise cancellation at the Einstein Telescope
Patrick Schillings, Johannes Erdmann
Newtonian noise is expected to be the dominating noise source for low frequencies at the Einstein Telescope. It originates from seismic waves that cause density fluctuations in the…
NNNN: Neural Networks for Newtonian Noise Mitigation at the Einstein Telescope
Jan Kelleter, Patrick Schillings, Jonathan Kuckert +4
The gravitational effects of seismic waves, so-called Newtonian noise, will likely limit the low-frequency sensitivity of future ground-based gravitational wave detectors, such as…
A numerical framework for Newtonian-noise estimation at the Einstein Telescope: 2-D simulations beyond the plane-wave approximation
Patrick Schillings, Shi Yao, Johannes Erdmann +1
The Einstein Telescope (ET) is a third-generation underground gravitational-wave observatory designed to extend the detection sensitivity down to a few Hertz. Newtonian noise is ex…
