Increasing the bandwidth of resonant gravitational antennas: The case of Explorer
P. Astone, D. Babusci, M. Bassan +22
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 upgrad…
Energetic Cosmic Rays observed by the resonant gravitational wave detector NAUTILUS
P. Astone, M. Bassan, P. Bonifazi +19
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 greater tha…
All-sky incoherent search for periodic signals with Explorer 2005 data
P. Astone, D. Babusci, M. Bassan +31
The data collected during 2005 by the resonant bar Explorer are divided into segments and incoherently summed in order to perform an all-sky search for periodic gravitational wave…
All-sky search of NAUTILUS data
P. Astone, M. Bassan, P. Bonifazi +33
A search for periodic gravitational-wave signals from isolated neutron stars in the NAUTILUS detector data is presented. We have analyzed half a year of data over the frequency ban…
Oxygen contamination in liquid Argon: combined effects on ionization electron charge and scintillation light
R. Acciarri, M. Antonello, B. Baibussinov +30
A dedicated test of the effects of Oxygen contamination in liquid Argon has been performed at the INFN-Gran Sasso Laboratory (LNGS, Italy) within the WArP R&D program. Two detector…
Studying the coincidence excess between EXPLORER and NAUTILUS during 1998
D. Babusci, G. Cavallari, G. Giordano +4
The coincidences between EXPLORER and NAUTILUS during 1998 (Astone et al. 2001) are more deeply studied. It is found that the coincidence excess is greater in the ten-day period 7-…
Dark Matter searches using gravitational wave bar detectors: quark nuggets and newtorites
M. Bassan, E. Coccia, S. D'Antonio +10
Many experiments have searched for supersymmetric WIMP dark matter, with null results. This may suggest to look for more exotic possibilities, for example compact ultra-dense quark…
Initial operation of the International Gravitational Event Collaboration
G. A. Prodi, I. S. Heng, Z. A. Allen +46
The International Gravitational Event Collaboration, IGEC, is a coordinated effort by research groups operating gravitational wave detectors working towards the detection of millis…
Search for correlation between GRB's detected by BeppoSAX and gravitational wave detectors EXPLORER and NAUTILUS
P. Astone, M. Bassan, P. Bonifazi +24
Data obtained during five months of 2001 with the gravitational wave (GW) detectors EXPLORER and NAUTILUS were studied in correlation with the gamma ray burst data (GRB) obtained w…
Study of the coincidences between the gravitational wave detectors EXPLORER and NAUTILUS in 2001
P. Astone, D. Babusci, M. Bassan +23
We report the result from a search for bursts of gravitational waves using data collected by the cryogenic resonant detectors EXPLORER and NAUTILUS during the year 2001, for a tota…
Comments on the 2001 run of the EXPLORER/NAUTILUS gravitational wave experiment
P. Astone, D. Babusci, M. Bassan +22
The recently published analysis of the coincidences between the EXPLORER and NAUTILUS gravitational wave detectors in the year 2001 (Astone et al. 2002) has drawn some criticism (F…
