Observations with a low-temperature, resonant mass, gravitational radiation detector

Abstract

A highly sensitive antenna's output noise level is used to establish a new observational upper limit on the flux of 1 kHz gravity wave bursts. The data employed were from 74 days of operation, and they demonstrate that the detector was being excited by pulses with non-Gaussian statistics. The absence of corresponding veto signals shows that the pulses contained only modest power at the second harmonic frequency of 1680 Hz.
