Vahe A. Petrosyan  – brief biography

  Physicist, Doctor of astronomy (1967), Professor (1980)

Foreign member of the National Academy of Sciences of RA (2008)


The main areas of activity cover many  topics in the broad area of theoretical astrophysics nd cosmology, with a strong focus on high-energy astrophysical processes. Cosmological studies deal with global properties of the universe, where the main focus is the understanding of the evolution of the universe at high redshifts, through studies of the evolutions of population of sources such as galaxies and quasars or active galactic nuclei, gamma-ray bursts, using new statistical techniques developed in collaboration with Prof. B. Efron of the Department of Statistics. Another area of research is the use of gravitational lensing in measuring mass in the universe. High-energy astrophysics research involves interpretation of non-thermal astronomical sources where particles are accelerated to very high energies and emit various kinds of radiation. These processes occur on many scales and in all sorts of objects: in the magnetosphere of planets, in the interplanetary space, during solar and stellar flares, in the accretion disks and jets around stellar-size and super-massive black holes, at centers of galaxies, in gamma-ray bursts, in supernovae, and in the intra-cluster medium of clusters of galaxies. Plasma physics processes common in all these sources for acceleration of particles and their radioactive signature is the main focus of the research here. He is the author of 250 scientific articles. Under his leadership were protected master’s and more than thirty undergraduate and 7 graduate theses.

Current areas of focus:

– Evolution of gamma-ray bursts and its implication for the early universe
– Evolution of blazers and quasars and their implications for super-massive black holes in the centers of galaxies
– Physics of particle acceleration in general magnetized astrophysical plasmas
– Development of new inversion techniques for determining the basic properties of acceleration mechanisms directly and non-parametrically from observations of high energy X-rays and gamma-rays from solar flares
– Acceleration of particles in clusters of galaxies and other diffuse media such as recently discovered Fermi bubbles around the center of our galaxy

He is born on the 13 th of September 1938 in Arak, Iran (Sultanabad).

1963 – Graduated from Cornell University (Itaqa, New York state, USA).

1967-1969 – Research Fellow, California Institute of Technology

1969 – Lecturer at Cambridge University

1972-1979 – Stanford University, Assistant Professor

1980 – Stanford University, Professor

1981 – Concurrently worked in Florence, Italy,  US National Optical Astronomy Observatory (Arizona), Nordita (Copenhagen, Denmark), Meudon Observatory (France), the US space telescope science institute, the Institute for Advanced Studies at the University of Bochum (Germany). In 2008 he was elected a foreign member of the National Academy of Sciences of RA.
