Towards the Detection of the Nanohertz Gravitational-wave background
How do galaxies evolve? The European Pulsar Timing Array provides a significant step forward
The
European Pulsar Timing Array collaboration reports on the outcome of a
24 year observing campaign with five large-aperture radio telescopes in
Europe, resulting in a candidate signal for the since-long sought
gravitational wave background due to in-spiraling supermassive
black-hole binaries. The collaboration brings together teams of
astronomers around the largest European radio telescopes, as well as
groups specialized in data analysis and modelling of gravitational wave
signals. Among them are astrophysicists from the research group of Professor Dr. Joris Verbiest from the Faculty of Physics at Bielefeld University.Although a detection cannot be claimed yet, this represents a
significant step in the effort to finally unveil gravitational waves at
very low frequencies in the Nanohertz regime.
The results are presented online as refereed publication in the “Monthly Notices of the Royal Astronomical Society”.
