High frequency gravitational wave
Web1. The Emerging Field of Gravitational Wave Astronomy Gravitational-wave (GW) astronomy is poised to make revolutionary contributions to astronomy and physics during the next two decades. In particular, the low frequency GW region (10–5 to 1 Hz) is rich in guaranteed sources of strong gravitational waves and offers Web23 de jan. de 2001 · An electric charge shaken in an homogeneous stationary magnetic field produces both electromagnetic and gravitational waves (Gertsenshtein waves). We first study this process in a homogeneous medium with a refractive index n, expressing the gravitational wave as a simple functional of the electromagnetic field. Then, an …
