  • Singh, Avneet (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    (english) Gravitational waves (GW) are tiny oscillations in the fabric of space-time, first hypothesised within the framework of Einstein’s General theory of Relativity (GR) a little more than 100 years ago. The first ...
