Limburg, in the border region between Belgium, Germany and the Netherlands, has been
identified as the Euregio Meuse–Rhine candidate site for Einstein Telescope. The site …

Terrestrial gravity fluctuations produce so-called Newtonian noise (NN) which is expected to
limit the low frequency sensitivity of existing gravitational-waves (GW) detectors LIGO and …

Einstein Telescope (ET) is a proposed underground infrastructure in Europe to host future
generations of gravitational-wave (GW) detectors. One of its design goals is to extend the …

We present a novel inertial sensor designed and developed at Nikhef that features an
interferometric readout for a horizontal monolithic accelerometer. It is the first time this class …

Gravitational wave observatories have always been affected by tele-seismic earthquakes
leading to a decrease in duty cycle and coincident observation time. In this analysis, we …

Abstract The Euregio Meuse-Rhine border region of Belgium, Germany and the Netherlands
has been identified as a candidate site for hosting Einstein Telescope. Newtonian coupling …

We present a compact, vacuum compatible seismic attenuation system designed to isolate
five auxiliary optical benches for Advanced Virgo, a second generation gravitational wave …

This thesis work fits in the Newtonian noise (NN) cancellation framework for gravitational-
wave (GW) detectors of 2nd and 3rd generation. At frequencies below 20 Hz the NN affects …

In the present study, I table the first detailed estimation of the magnetic noise contribution to
the Advanced Virgo sensitivity to gravitational waves. I tackle the topic by performing …

The cryosphere encompasses the seasonally and perennially frozen parts of the earth and
its extent is both sensitive to and impacts upon the global climate through surface energy …
