TL;DR: In the ongoing analysis of the data obtained with NAUTILUS in coincidence with cosmic ray (c.r.) detectors as mentioned in this paper, the authors found new interesting results and proposed a new approach to detect gravitational wave (g.w.) signals.

TL;DR: In this paper, a procedure for the search of signals from periodic sources in the data of gravitational wave detectors was developed, which can be extended for any assumed position in the sky and for a more general all-sky search, with the proper frequency correction to account for spin-down and Doppler effects.
Abstract: We have developed a procedure for the search of signals from periodic sources in the data of gravitational wave detectors. We report here the analysis of one year of data from the resonant detector Explorer, searching for sources located in the Galactic Center ~GC!. No signals with amplitude greater than h 52.9310 224 ,i n the range 921.32‐921.38 Hz, were observed using data collected over a time period of 95.7 days, for a source located at a517.7060.01 h and d5229.0060.05 deg. Our procedure can be extended for any assumed position in the sky and for a more general all-sky search, with the proper frequency correction to account for the spin-down and Doppler effects.

TL;DR: In this paper, the authors search for coincidences with the cryogenic resonant gravitational wave detectors EXPLORER and NAUTILUS during a period of about six months (2 June-14 December 1998) for a total measuring time of 94.5 d, with the purpose of studying new analysis algorithms, based on the physical characteristics of the detectors.

TL;DR: In this paper, the passage of cosmic rays has been observed to excite mechanical vibrations in the resonant gravitational wave detector NAUTILUS operating at temperature of 100 mK, and a very significant correlation (more than ten standard deviations) is found.
