Talk

We highlight recent results from geophysical researches and applications conducted via measuring cosmic muons by HUN-REN Wigner RCP and University of Tokyo. Our main infrastructure is the Sakurajima Muography Observatory in Kyushu, Japan. It is a modular system that is operating with muon trackers based on gaseous detectors and scintillators. The SMO is monitoring the mass density changes...

34. Challenges in Newtonian noise estimations: rheological effects

Talk

Soil and rocks are not so elastic as expected, both present damped and delayed mechanical behavior, called viscoelasticity or rheology. Deviation of static and dynamic elasticity moduli of rocks can also be explained via rheology, furthemore, long term measurements prove that motion of the soil around underground facilities may be relevant even years after the construction. Although elastic...

51. A robotized environmental sensor array for gravitational wave observatory sites

Talk

A movable array of environmental sensors is intended for the feed-forward cancellation of the Newtonian noise generated by atmospheric density fluctuations and seismic displacements at the Virgo gravitational wave detector site, with the prospect of being used at the sites of future 3rd generation detectors.
Each robot unit is equipped with a seismic sensor - optionally also a microphone and...
