Galaxies & Cosmology department is a division of the Institute of Astronomy and National Astronomical Observatory at the Bulgarian Academy of Sciences.
We study the structure and evolution of galaxies, activity in galactic nuclei and related phenomena, and physiscal processes in the early Universe using both observational and theoretical approaches.
On the picture: True-colour image of the Seyfert galaxy NGC 7469 and its companion IC 5283. The gravitational interaction between the galaxies, resulting in a tidal tail in IC 5283, could trigger the nuclear activity in NGC 7469. The image is obtained with the 2-m telescope of the Rozhen NAO under subarcsecond seeing conditions. Observers: L. Slavcheva-Mihova & B. Mihov.
