Vahagn "Vahe" Gurzadyan (

WMAP data may provide evidence of violent pre-Big-Bang activity"[1]
paper with his colleague,
Cycles of Time
.

Gurzadyan was born in

Lebedev Physics Institute
at Moscow (1977–1980; 1980 PhD.), DSci in theoretical and mathematical physics (1988).

In 1989 he lectured on dynamical systems in four universities in Japan (Tokyo, Kyoto, Hiroshima, Fukui), and subsequently held visiting positions at the University of Sussex (1996–1997) and, since 2001, at Sapienza University of Rome. His father Grigor Gurzadyan, an Armenian astronomer pioneered space-based astronomy using satellites. His grandfather Ashkharbek Kalantar was a Russian Empire and Armenian archaeologist and historian, Fellow of Russian Imperial Archaeological Society and the keeper of the Asiatic Museum in St. Petersburg.[2]

Main research

The main topics of his research: chaos in non-linear systems, accretion onto massive black holes, stellar dynamics, observational cosmology.

Gurzadyan has papers predicting elliptical accretion disks formed in galactic nuclei at tidal disruption of stars near massive black holes;[3] the tidal mechanism currently is associated to the flares observed in AGN.[4]

He has shown (with Savvidy; Gurzadyan-Savvidy relaxation) the exponential instability (chaos) in spherical stellar systems and has derived the collective relaxation time.[5][6][7] He has formulated a list of 10 key problems in stellar dynamics[8][9] [10] He has proved a theorem (Gurzadyan theorem) on the most general functional form for the force satisfying the condition of identity of the gravity of the sphere and of a point mass located in the sphere's center. [11]

Cosmic microwave background indications for cosmic voids were obtained by Gurzadyan et al., including on the void nature of the Cold Spot,[12][13] confirmed by independent galaxy survey,[14] as of possibly largest known structure in the Universe.

Gurzadyan has suggested and initiated the use of Compton Edge method for high accuracy testing of the light speed isotropy and the

Lorentz invariance at GRAAL experiment in European Synchrotron Radiation Facility (Grenoble); the obtained limit became a reference number for Special Relativity extension models.[15][16][17]

Other topics

Gurzadyan has invented

Arecibo
-type antenna to Galactic distances.

Gurzadyan and Penrose discussed

cosmic microwave background radiation
transferring information from pre-Big Bang aeon to ours.

He led a study with geneticists in Duke University introducing a new method to detect somatic mutations in genomic sequences,[21] in proposing bath-quantum system viewpoint on the relation of thermodynamic and cosmological arrows of time.[22]

Revealing the chronology of ancient world with astronomical dating

Gurzadyan's collaboration with archaeologists on the Chronology of the ancient Near East[23] and his analysis of the Venus tablet of Ammisaduqa and of lunar eclipses of 3rd dynasty of Ur led to the introducing of the Ultra-Low chronology of the 2nd-millennium ancient Near East.[24]

He identified the

Crab nebula) in Armenian medieval chronicle of Hetum (Hayton of Corycus) and Cronaca Rampona.[26]

Activities

Member of

The European Physical Journal Plus (Springer)
and of book series 'Advances in Astronomy and Astrophysics' (Taylor & Francis, UK). Fellow of the Royal Astronomical Society (UK).

Speaker at XXII

Solvay conference
on physics, keynote speaker at IXth Swiss Biennial on Science, Technics + Aesthetics on "The Large, The Small and the Human Mind", lecturer at Xth Brazilian School of Cosmology and Gravitation.
