Experimental gravitation at very low temperatures.
Abstract
Gravitational waves and "gravitomagnetic" components of general-relativistic gravitation have as yet escaped direct detection with laboratory experiments. The authors report on progress in their attempt to make feasible a ground based cryogenic experiment aimed to measure the Lense-Thirring-Schiff dragging of inertial frames due to the rotating earth, which is the main component of the local "gravitomagnetic" field. They present the goals of the experiment AURIGA, to be set up at LNL: an ultracryogenic, T ≈ 0.1K, resonant antenna, M ≅ 2300 kg, will be operated in continuous coincidence with the similar NAUTILUS at CERN to search for gravitational waves impulses from galaxies of the Local Group.
