Resonant-mass gravitational wave detectors are reviewed from the concept of gravitational
waves and its mathematical derivation, using Einstein's general relativity, to the present …

Our Moon is by far the easiest natural, extraterrestrial celestial object for us to reach, and
many space agencies, in particular the China National Space Administration, have …

SCHENBERG is a resonant-mass gravitational wave detector built in Brazil. Its spherical
antenna, weighting 1.15 t, is connected to the outside world by a suspension system whose …

Schenberg is a resonant-mass gravitational wave detector developed by the Brazilian
Graviton group that is sensitive to a central frequency near 3200 Hz with bandwidth around …

The resonant-mass gravitational wave detector SCHENBERG was designed by the Brazilian
group Graviton to be sensitive to a central frequency nearing 3200 Hz and a bandwidth of …

We show that the interaction of a gravitational wave with a spherical resonant-mass antenna
changes the antenna's shape to that of an ellipsoid. These changes in shape always …

An experiment to measure the speed of gravity is being planned. For this purpose, a
numerical method was developed for the optimization of a composite quadrupole mass at …

" Mario Schenberg" is a spherical gravitational wave (GW) detector that will be part of a GW
detection array of two detectors. Another one is been built in The Netherlands. Spherical …

The most important features of the proposed spherical gravitational wave detectors are
closely linked with their symmetry. Hollow spheres share this property with solid ones …

We report the results of a theoretical and experimental study of a spherical gravitational
wave antenna. We develop a number of techniques to deconvolve the data from a set of …
