Data from 15 years provide first convincing evidence for the existence of low-frequency background noise from gravitational waves in the universe / Physicist Kai Schmitz from the University of Münster involved in consortium

Astrophysicists have for the first time found convincing evidence for the existence of gravitational waves that oscillate with periods ranging from years to decades. This is according to five papers published June 29 in The Astrophysical Journal Letters. To do so, the researchers evaluated 15 years of data collected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). Kai Schmitz of the University of Münster and Andrea Mitridate of DESY in Hamburg are involved in one of the research articles. ...
