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).
With the start of the SRG all-sky survey, eROSITA promises most accurate maps of the X-ray sky ever11.12.2019
Launched from Baikonur on July 13th 2019 to the second Sun-Earth Lagrange point (L2), the Russian-German SRG mission has now started its main task. On December 8th, after an extensive program of commissioning, calibration and performance verification of its two X-ray telescopes (ART-XC and eROSITA), the satellite has begun observing the sky in continuous scanning mode.read article

Successful launch for eROSITA X-ray telescope13.07.2019
Today at 14:31 (on 13 July 2019), the Russian-German Spektrum-Roentgen-Gamma (SRG) space mission successfully lifted off from the Baikonur cosmodrome. On-board is the eROSITA X-ray telescope, which was developed and built by a consortium of German institutes supported by Deutsches Zentrum für Luft- und Raumfahrt (DLR) and led by the Max Planck Institute for Extraterrestrial Physics (MPE). Astronomers from the University of Bonn are involved in the scientific preparation and exploitation. 1.5 million kilometres from Earth, eROSITA will perform a deep survey of the entire X-ray sky over the next four years, providing the first ever deep imaging survey of the sky at soft and hard X-rays.read article

Observations challenge cosmological theories04.10.2018
A study from the University of Bonn examines how well current measurements match the predictions of the standard model of cosmology. Recent observations create a puzzle for astrophysicists: since the big bang, less galaxy clusters have formed over time than was actually expected. Physicists from the university of Bonn have now confirmed this phenomenon. For the next three years, the researchers will analyze their data in even greater detail. This will put them in a position to confirm whether the theories considered valid today need to be reworked. The study is part of a series of 20 publications which appear in the professional journal "Astronomy and Astrophysics".read article
