... A color image of the Andromeda galaxy always takes a little of my breath away: its golden yellow center, its bluish gossamer arms, its small, burr-like, fuzzy elliptical companion, M32. ... The beautiful images of Andromeda are a start; they give us a sense of what good form is for galaxies like our own. ... Meanwhile, radio astronomers have peered to the very center of the Galaxy and the hungry black hole there; the long radio wavelengths cut right through the dense underbrush of the Galactic...

In this framework, an international collaboration between INAF-OAA, INAF-Brera, INAF-OATs, the University for Science and Technology of China-Hefei, the University of Ferrara, and the University of Massachusetts-Amherst, is undertaking a new cluster survey using an X-ray facility that was never exploited before for this goal: the X-ray Telescope (XRT) onboard the Swift satellite...

... Radio source identifications . The Web-server of the Special Astrophysical Observatory supports the mirror version of the Clusters of Galaxies database . At present only the data about radio sources in ACO clusters of galaxies are reasonably complete, while only restricted optical information is in our database. Later on, we also intend to include X-ray data and data about brightest cluster galaxies (BCG). ... ACO: radio optic ( for example, A0690 and " optic "), . ...
