CURRENT
PROJECTS AT THE BYURAKAN OBSERVATORY (2000-2008)
Altogether, 97 large and small projects are currently
active in Byurakan; many of them are in collaboration with foreign countries or
other institutions in Armenia. Most of the projects are led by the Byurakan
astronomers (principal investigators, PIs).
Below is the list of all current projects (sorted by
fields of investigations); titles, main research topics, investigators,
collaborations, number of publications and link to the list of papers, grants
