On January 1, 1993, the institute was merged with the Astronomic Observatory, the Ørsted Laboratory and the Geophysical Institute. The new resulting institute retained the name Niels Bohr Institute.

Research sections

Research at the Niels Bohr Institute is organised in ten research sections covering a broad range of physics, i.e. astrophysics, biophysics, solid state physics, geophysics, particle physics and e-science.
