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 …

The possible signature of chaotic behavior of multiparticle production in nucleus–nucleus
collision has been investigated with the help of a new parameter, the entropy index μq. This …

Cosmic-ray showers interacting with the resonant mass gravitational wave antenna
NAUTILUS have been detected. The experimental results show large signals at a rate much …

We review the main features and the perspectives of the resonant-mass gravitational wave
detectors. Bar detectors have been taking data for the last few years with burst sensitivity h≃ …

We report on the present scientific run (04–05) of the two detectors EXPLORER and
NAUTILUS. The 04–05 run of the two detectors started in March 2004. The strain sensitivity …

The two cryogenic resonant bar detectors of the ROG Collaboration, EXPLORER and
NAUTILUS, have been taking data continuously with a high duty cycle for several years. We …

The ultra-cryogenic gravitational wave detector NAUTILUS is gathering data in Frascati
(Rome), in its second science run since June 1998. The measured strain sensitivity at the …

Resonant gravitational wave detectors with an observation bandwidth of tens of hertz are a
reality: the antenna Explorer, operated at CERN by the ROG Collaboration, has been …

The cryogenic resonant gravitational wave detectors NAUTILUS and EXPLORER, made of
an aluminum alloy bar, can detect cosmic ray showers. At temperatures above 1K, when the …

Results of long-term measurements of electric charge located on the fused silica test mass
suspended by fused silica fibers are presented. The charge was measured by means of the …
