Jet Activity in the Central Super Massive Black Hole of the Milky Way in 4th and 14th centuries and millennium periods of climate change

Olga I. Piskounova, Irina V. Tamarkina

TL;DR

The paper investigates whether historical reports of daytime X-crosses can be explained by jets from the Milky Way's central supermassive black hole. It combines archival narratives with sky-mapping using Wolfram Astronomy to test spatial and temporal consistency of four events (312 CE, 351 CE, 1317 CE, 1377 CE). The authors argue that each event corresponds to back-to-back jets crossing the Galactic disk projection and that a roughly thousand-year recurrence may reflect periodic center activity linked to climate variations. The work highlights potential observational signatures of MW center activity in the past and motivates further cross-cultural and astrophysical investigations.

Abstract

This paper discusses the historical evidence for the light jets from the central Super Massive Black Hole of Galaxy in the 4th and 14th centuries. We suggest that the apparitions of a "lightening cross" recorded in 312, 351, 1317 and 1377 years were caused by the line of two jets beamed back-to-back from the center of Milky Way (MW), which is crossing the visible projection of the Galaxy disk. All historical accounts give precise time and geographical locations, where from X-crosses was seen: in the vicinity of Rome, in Jerusalem, in Tver' (the vicinity of Moscow) and in night sky over Moscow, respectively). The positions of the Sun (or the Moon) were also mentioned in the Middle Age manuscripts. These positions coincide with the location of the MW center on the sky map in these specific places and dates, as it is shown with the help of Wolfram Astronomy visualization instruments. We suggest that the gap between jet activity events is about thousand years. The X cross in the sky was mentioned by Plato in {\it Timaeus}\cite{plato}, but he cannot be eyewitness and could only take this from the narratives of older ancient sages. The X cross pictures are multiply stamped on Roman coins. It is also important that the 4th and the 14th centuries were times when the climate vent colder. The processes in Galaxy are often periodic because of orbital movements, so we should consider the thousand years periods in the climate changes as well.
