Extragalactic Astronomy and Cosmology


Extragalactic astronomy at INAF OAS Bologna comprises several research groups. Their studies include a wide range of subjects, from the structure and evolution of “normal” galaxies, to the physical properties of active galactic nuclei (AGNs) and galaxy clusters, to large-scale structures and cosmology.

These studies are based on multi-wavelength (radio, infrared, optical and X-ray) observations taken with the most advanced instruments available today: the ESO optical/NIR telescopes (including VLT), the Hubble Space Telescope, the X-ray satellites Chandra and XMM-Newton, the Westerbork, VLA and ATCA radio-telescopes.

Observations are then compared to theoretical predictions in order to determine the physical processes that lead to a given observational property. Among the other things, this enables us to put constraints on many cosmological parameters as well as on the scenario of structure formation and evolution.
