Nonequilibrium steady state fluctuations in actively cooled resonators
M. Bonaldi, L. Conti, P. De Gregorio +15
We analyze heat and work fluctuations in the gravitational wave detector AURIGA, modeled as a macroscopic electromechanical oscillator in contact with a thermostat and cooled by an…
Feedback cooling of the normal modes of a massive electromechanical system to submillikelvin temperature
A. Vinante, M. Bignotto, M. Bonaldi +13
We apply a feedback cooling technique to simultaneously cool the three electromechanical normal modes of the ton-scale resonant-bar gravitational wave detector AURIGA. The measurin…
Principles of wide bandwidth acoustic detectors and the single-mass DUAL detector
Michele Bonaldi, Massimo Cerdonio, Livia Conti +7
We apply the standard theory of the elastic body to obtain a set of equations describing the behavior of an acoustic Gravitational Wave detector, fully taking into account the 3-di…
Upper limits on gravitational waves emission in association with the Dec 27 2004 giant flare of SGR1806-20
L. Baggio, M. Bignotto, M. Bonaldi +20
At the time when the giant flare of SGR1806-20 occurred, the AURIGA "bar" gw detector was on the air with a noise performance close to stationary gaussian. This allows to set relev…
3-mode detection for widening the bandwidth of resonant gravitational wave detectors
L. Baggio, M. Bignotto, M. Bonaldi +16
We have implemented a novel scheme of signal readout for resonant gravitational wave detectors. For the first time, a capacitive resonant transducer has been matched to the signal…
Selective readout and back-action reduction for wideband acoustic gravitational wave detectors
M. Bonaldi, M. Cerdonio, L. Conti +3
We present the concept of selective readout for broadband resonant mass gravitational wave detectors. This detection scheme is capable of specifically selecting the signal from the…
