People involved at OAB:
Observational extragalactic astronomy has traditionally been one of
the main themes of research at the Bologna Observatory. It includes
a wide range of subjects, from the structure and evolution of ``normal"
galaxies, to the physical properties of active galactic nuclei
(AGNs) to observational cosmology.
The extragalactic research at the Bologna Observatory is characterized
by the lack of ``wavelength chauvinism": while optical astronomy is and
will remain important at the Observatory, some of the scientific staff
specialize in X-ray observations of AGNs, and others find their main
interest in radio studies of galaxies and quasars.
Much of this research is based on an intensive use of the most advanced
instruments available today: the X-ray satellites Beppo-SAX, Chandra and
XMM-Newton, the ESO optical telescopes (including VLT), the infrared satellite
ISO, the Westerbork, VLA and ATCA radiotelescopes.
