Gregory Markari (Markarovich) Garibian (December 13, 1924 – June 8, 1991) was a Soviet Armenian physicist, academician-secretary of the Department of Physics and Mathematics of the Armenian Academy of Sciences (AS)(1973–1991). He is known for developing the Theory of Transition Radiation and showing the feasibility of functional transition radiation detectors (TRDs) .
G.M.Garibian was born in 1924 in Tiflis (now - Tbilisi, Georgia) in a family of a Medical Doctor and a homemaker. Eventually the family moved to Baku (Azerbaijan) where Garibian got his general education. In 1943 he graduated from school in Baku and went to Moscow. Physical science was Garibian's passion in life. Even at a very young age he followed news in the world of physics and was very excited when in 1942 he learned about the Alikhanian brothers’ expedition to Mount Aragats (Armenia) in order to search for protons in cosmic rays. Garibian was accepted into the Department of Physics and Mathematics of Moscow State University which he graduated from in 1948 immediately to leave for Yerevan and join the Yerevan Physics Institute, which was founded by Artyom Alikhanian in 1943. After that time Garibian dedicated himself to scientific research in Theoretical physics, in the fields of Quantum electrodynamics, Cosmic rays, and High energy particles. All his life he worked at the Yerevan Physics Institute consecutively as Researcher, Scientific Secretary of the Institute, Deputy Director and Head of Laboratory. He actively participated in the creation of the Yerevan Synchrotron and also in the establishment of high altitude Cosmic Ray stations on Mount Aragats.
Garibian’s main scientific achievement was the discovery of X-Ray Transition Radiation and the development of the Theory of Transition Radiation . He also showed the feasibility of a functional Transition Raditation Detector (TRD) - a tool for identification of high energy ultrarelativistic particles.
