Welcome to the home page of the

Rome 1 group of the ROG Gravitational Wave Experiment ( Explorer and Nautilus detectors )

We are researchers of

INFN, Rome

The goal of the experiment is to look for gravitational waves

Explorer Nautilus Gravitational Wave Antennas

    Some pictures of Explorer,Nautilus detectors

    Explorer and Nautilus noise spectral densities

Papers from the Spires data base are here

Since the year 2001, the bandwidth of the Explorer detector has increased. Also the bandwidth of Nautilus has increased, since the year 2003. The new system is described here:
