Irakli Simonia (Georgian: ირაკლი სიმონია; October 22, 1961 — ) is a Georgian Georgian astrophysicist and specialist in the ancient astronomy. Irakli Simonia graduated physics and mathematics department of Tbilisi State Pedagogical University in 1985, with MS in physics. He received a PhD in cometary astrophysics from Georgia Academy of Sciences in 1998. His scientific supervisor was Professor Klim Churyumov. During 1988 – 2008 he was a researcher at Abastumany Astrophysical Observatory. Since 2008 he is an Associate Professor of Astronomy at the School of Natural Sciences and Medicine of Ilia State University. During 2009 – 2014 he was an adjunct professor at James Cook University, Australia.

Scientific activity[edit]

Irakli Simonia is author of more than 80 scientific papers in fields of astrophysics, cosmochemistry and the ancient astronomy. He investigates physics and chemistry of cometary ice and dust; interplanetary dust; Trans-Neptunian Objects; mineral and icy dust of the galactic nebula and other objects. He investigates also astromegalithes; ethno-cosmological peculiarities of small artifacts; and the medieval astronomical manuscripts. He developed a new theory of photoluminescence of cosmic ice and dust. Particularly he suggested a new model of frozen hydrocarbon particles of cometary atmospheres and galactic nebula. He described the properties of these particles in the form of icy micro-grains – frozen mixtures of aromatic and aliphatic hydrocarbons, and applied this theory and model to the study of ice of comets 122P/de Vico, 153P/Ikeya-Zhang and nebula CED 201. He demonstrated that previously unidentified emissions of optical spectra of these comets and nebula represent the photoluminescence of frozen hydrocarbon particles of these objects..[1] [2] [3] [4] [5] [6] [7] [8].

He considered thermoluminescence properties of solid cometary matter, including carbonaceous dust [9].

He demonstrated (together with a co-author) that the frozen hydrocarbon matter of comets, including relict matter, may contain prebiotics or their structural analogues, which luminesce under the influence of external radiation [10].

Irakli Simonia suggested (together with a co-author) a new explanation of visible reddening of Trans-Neptunian Objects as double scattering of sunlight by nanometric dust of an ecliptic dust cloud [11].

He suggested new mechanism of the formation of diffuse interstellar bands in the spectra of galactic objects – a phenomenon of interstellar quasiline absorption [12].

The investigations conducted by I.Simonia in the field of ancient astronomy cover both the history of astronomy and archaeoastronomy [13] [14]. He investigated the development of the cosmological worldview and astronomical knowledge in the ancient Georgia during the period of 16th century BC – 18th century AD [15] [16].

He proposed (together with a co-authors) a concept of “solar stations” as megalithic multifunctional complexes of ritual, observational, and calendar significance [17] [18] [19].

He investigated a number of Georgian, Persian and Arabic astronomical manuscripts (9-19 centuries) and published (together with a co-authors) an e-book – a scientific database on Astronomical Manuscripts in Georgia [20] [21]

Academic activity[edit]

Irakli Simonia leads courses in astronomy, molecular astrophysics, and archaeoastronomy. He supervises PhD students. He created the world’s first PhD program in archaeoastronomy at Ilia State University.
