Description
Gravitomagnetic effects are some of the most peculiar predictions of General Relativity. It is known that spinning astrophysical sources drag space-time around them, a phenomenon known as frame-dragging. The Lense- Thirring effect is one of its consequences. It consists in the precession (with respect to the fixed-stars) of the rotation axis of a test-gyroscope in the gravitational field of a spinning mass. The INFN experiment GINGER (Gyroscopes IN GEneral Relativity) foresees the construction of a ground-based system of large-frame ring laser gyros with the aim of measuring the Lense-Thirring effect generated by the Earth's rotation. In this poster we describe the physical principles behind a ring laser gyro and the recent results achieved by the GINGER collaboration. In addition, various applications will be illustrated, with a focus on research in fundamental Gravitation Physics.
