IAU Symposium #194: Activity in Galaxies and Related Phenomena

Devoted to V.A. Ambartsumianís 90th anniversary

 

August 17-21, 1998, Byurakan, Armenia

 

 

IAU Symp. 194 was devoted to V.A. Ambartsumianís 90th anniversary, who was the first astrophysicist who understood what a rich treasure was hidden under the activity phenomena in galaxies. In 50-s he began with his collaborators his systematic investigations in this field and obtained really very impressive results concerning various evidences of the activity in galaxies. In the last forty years a vast amount of observational data was accumulated. Moreover, nowadays collection of new data takes place with an increasing rate. And now when a great quantity of observational data on active phenomena is provided owing to new technology it was necessary to discuss the results more often. There was a need to display the main tendencies in physical explanations of the phenomena in question as well as in the observational possibilities. Ground-based new large telescopes and especially HST provided astronomers not only with a new amount of data but gave them qualitatively new type information which should be comprehended in connection with the established physical laws.

100 scientists from 22 countries (USA, Japan, China, Mexico, Australia, UK, Germany, France, Italy, Netherlands, Belgium, Spain, Switzerland, Ireland, Bulgaria, Brazil, Egypt, Russia, Ukraine, Kazakhstan, Georgia, and Armenia) participated in the symposium, including 70 foreign (13 from former USSR), and 30 from Armenia. Among the participants, there were a number of distinguished scientists, such as Halton Arp, Kenneth Kellermann, Jack Sulentic, Daniel Weedman, David Sanders, Suzy Collin-Zahn, Malcolm Longair, Patrick Osmer, Vahe Petrosian, Yervant Terzian, Francesco Bertola, Felix Mirabel, Ian Robson, Philippe Veron, Gerard Lelievre, Thierry Courvoisier, Richard Lovelace, Alexei Fridman, Michael Dopita, and others.

 

Altogether 136 contributions were presented, including 27 invited reviews on the invitation of the SOC of the Symposium (by H. Arp (2), W. Baan, A. Boyarchuk, Georg Brutian, S. Collin-Zahn, T. Courvoisier, M. Dopita, A. Fridman, T. Kawaguchi, K. Kellermann, E. Khachikian, J. Krolik, M. Longair, R. Lovelace, F.D. Macchetto, F. Mirabel, P. Osmer, V. Petrosian, I. Robson (2), M. Romanova, R. Sambruna, D. Sanders, M. Turatto, Y. Terzian, and D. Weedman), 25 contributed oral talks, and 84 posters.

 

The IAU Symp. 194 in Byurakan was important from the point of view of putting together various multiwavelength data on AGN and their interpretation in view of the unified model. The experts discussed multiwavelength properties of different AGN and elaborated strategy for their further studies.
