Some context: The Cimmerians (also Kimmerians; Greek: Kimmerioi, Kimmerioi) were an ancient people, who appeared about 1000 BC  and are mentioned later in 8th century BC in Assyrian records. Probably originating in the Pontic steppe and invading by means of the Caucasus, they are likely to be those who in c. 714 BC assaulted Urartu, a state in north eastern Anatolia subject to the Neo-Assyrian Empire. They were defeated by Assyrian forces under Sargon II in 705 and turned towards Anatolia, conquering Phrygia in 696/5. They reached the height of their power in 652 after taking Sardis, the capital of Lydia; however an invasion of Assyrian controlled Anshan (Persia) was thwarted.
The supposed origin of the Cimmerians north of the Caucasus at the end of the Bronze Age loosely corresponds with the early Koban culture (Northern Caucasus, 12th to 4th centuries BC), but there is no compelling reason to associate this culture with the Cimmerians specifically.  There is a tradition in archaeology of applying Cimmerian to the archaeological record associated with the earliest transmission of Iron Age culture along the Danube to Central and Western Europe, associated with the Cernogorovka (9th to 8th centuries) and Novocerkassk (8th to 7th centuries) between the Danube and the Volga. This association is "controversial", or at best conventional, and is not to be taken as a literal claim that specific artifacts are to be associated with the "Cimmerians" of the Greek or Assyrian record.  The use of the name "Cimmerian" in this context is due to Paul Reinecke, who in 1925 postulated a "North-Thracian-Cimmerian cultural sphere" (nordthrakisch-kimmerischer Kulturkreis) overlapping with the younger Hallstatt culture of the Eastern Alps. The term Thraco-Cimmerian (thrako-kimmerisch) was first introduced by I. Nestor in the 1930s. Nestor intended to suggest that there was a historical migration of Cimmerians into Eastern Europe from the area of the former Srubna culture, perhaps triggered by the Scythian expansion, at the beginning of the European Iron Age. In the 1980s and 1990s, more systematic studies[by whom?] of the artifacts revealed a more gradual development over the period covering the 9th to 7th centuries, so that the term "Thraco-Cimmerian" is now rather used by convention and does not necessarily imply a direct connection with either the Thracians or the Cimmerians.
Are there any notable archaeologists that have researched the Cimmerians?
A: The use of the name "Cimmerian" in this context is due to Paul Reinecke,
Some context: Tilak was born in a Marathi Chitpavan Brahmin family in Ratnagiri as Keshav Gangadhar Tilak, as mentioned above. In headquarters of the eponymous district of present-day Maharashtra (then British India) on 23 July 1856. His ancestral village was Chikhali. His father, Gangadhar Tilak was a school teacher and a Sanskrit scholar who died when Tilak was sixteen.
On 30 April 1908, two Bengali youths, Prafulla Chaki and Khudiram Bose, threw a bomb on a carriage at Muzzafarpur, to kill the Chief Presidency Magistrate Douglas Kingsford of Calcutta fame, but erroneously killed two women traveling in it. While Chaki committed suicide when caught, Bose was hanged. Tilak, in his paper Kesari, defended the revolutionaries and called for immediate Swaraj or self-rule. The Government swiftly charged him with sedition. At the conclusion of the trial, a special jury convicted him by 7:2 majority. The judge, Dinshaw D. Davar gave him a six years jail sentence to be served in Mandalay, Burma and a fine of Rs 1,000. On being asked by the judge whether he had anything to say, Tilak said:  All that I wish to say is that, in spite of the verdict of the jury, I still maintain that I am innocent. There are higher powers that rule the destinies of men and nations; and I think, it may be the will of Providence that the cause I represent may be benefited more by my suffering than by my pen and tongue.  In passing sentence, the judge indulged in some scathing strictures against Tilak's conduct. He threw off the judicial restraint which, to some extent, was observable in his charge to the jury. He condemned the articles as "seething with sedition", as preaching violence, speaking of murders with approval. "You hail the advent of the bomb in India as if something had come to India for its good. I say, such journalism is a curse to the country". Tilak was sent to Mandalay from 1908 to 1914. While imprisoned, he continued to read and write, further developing his ideas on the Indian nationalist movement. While in the prison he wrote the Gita Rahasya. Many copies of which were sold, and the money was donated for the Indian Independence movement..
