The Digitized First Byurakan Survey

Area 02 – Scienze fisiche

In the framework of a collaboration between the grouup of High Energy Cosmic Sources (SCAE) within the Department of Physics at the University La Sapienza, and scientists of the Byurakan Astrophysical Observatory, it was decided to preserve the large collection of spectral astronomical plates known as the First Byurakan Survey (FBS) by transforming it into an electronic archive, accessible by computers through the World Wide Web. This collection was obtained by Benjamin E. Markarian and collaborators in the years 1965–80 and covers a large part of the sky observable at our latitudes. The Infrared Projects Group within the Department of Astronomy at Cornell University (USA) joined this project. The project has been carried on during several years and required a substantial effort, largely sustained by funding from the Sapienza University and the Italian Ministry of Research (MIUR), with additional support from the US Civilian and Research Development Foundation. Today the results are freely accessible to the world astronomical community through a dedicated web interface and include digitization of 90% of the FBS. This book contains several contributions which describe the history of the FBS, the most important results obtained with it, and presents the electronic version (Digitized First Byurakan Survey, DFBS).Enrico Massaro and Roberto Nesci are professors of astrophysics at the University of Roma “La Sapienza”. They work mainly in multifrequency observations of blazars.Areg Mickaelian works at the Byurakan Astrophysical Observatory and is copresident of the Armenian Astronomical Society. He worked on the First and Second Byurakan Surveys and on the identification and classification of large samples of galactic and extragalactic objects.Daniel Weedman, professor of Astronomy at the Cornell University, works in optical and infrared astronomy. He developed the original classification for Seyfert galaxies and discovered the starburst galaxies.Contributions of D.J. Barry, G. Cirimele, L. D’Amante, L.K. Erastova, S. Gaudenzi, P. Germano, K.S.
