Welcome to AIfA!
Welcome to the AIfA! The Argelander-Institut für Astronomie (AIfA) is an
academic, research and educational institute that is part of the
Department of Physics and Astronomy at the University of Bonn, Germany.
We conduct cutting-edge research over a broad range of theoretical and
observational topics from stars to cosmology, as you can see from our
Research page. Many national and international collaborations
have partners in the AIfA, for example we have a close relationship with
our neighbour, the Max-Planck Institut fuer Radioastronomie (MPIfR).

A galactic test will clarify the existence of dark matter
25.06.2018A new study found a way to determine whether the mysterious “star putty” really exists. Researchers at the University of Bonn and the University of California at Irvine used sophisticated computer simulations to devise a test that could answer a burning question in astrophysics: is there really dark matter? Or does Newton's gravitational law need to be modified? The new study, now published in the Physical Review Letters, shows that the answer is hidden in the motion of the stars within small satellite galaxies swirling around the Milky Way.
