Abstract We suggest an explanation of a sharp increase in the abundance of cosmogenic radiocarbon found in tree rings dated AD 775. The increase could originate from high-energy irradiation of the atmosphere by a galactic gamma-ray burst. We argue that, unlike a cosmic ray event, a gamma-ray burst does not necessarily result in a substantial increase in long-lived 10 Be atmospheric production. At the same time, the 36 Cl nuclide would be generated in the amounts detectable in the corresponding… Expand

Impulsive event probability in the radiocarbon record in VIII - XI centuries
The abundance of cosmogenic isotopes in natural samples is the main source of information about past variations of cosmic ray intensity, in the solar activity and in the strength of the geomagnetic… Expand
The cosmic-ray events around AD 775 and AD 993 : assessing their causes and possible effects on climate
Miyake et al. (2012, 2013) discovered rapid increases of 14C content in tree rings dated to AD 774-5 and AD 992-3 which were attributed to unprecedented cosmic-ray events. These extreme particle… Expand
“Isotopic footprints” of gamma-ray and proton events and anomalous signal in radiocarbon in 775 AD

A rapid cosmic-ray increase in BC 3372–3371 from ancient buried tree rings in China
TLDR
A rapid increase of 14C is observed in an ancient buried tree from BC 3372 to BC 3371, and it is suggested that this event could originate from a large solar proton event. Expand
Causation of Late Quaternary Rapid-increase Radiocarbon Anomalies
Brief (less than 100 years) rapid-increase anomalies in the Earth's atmospheric radiocarbon production have previously been attributed to either gamma photon radiation from supernovae or to cosmic… Expand
Multiradionuclide evidence for the solar origin of the cosmic-ray events of ᴀᴅ 774/5 and 993/4
TLDR
Evidence is provided that these peaks in the atmospheric radiocarbon (14C) concentration at AD 774/5 and 993/4 were most likely produced by extreme solar events, based on several new annually resolved 10Be measurements from both Arctic and Antarctic ice cores. Expand
Solar system exposure to supernova γ radiation
Abstract Planetary habitability may be affected by exposure to γ radiation from supernovae (SNe). Records of Earth history during the late Quaternary Period (40 000 years to present) allow testing… Expand
Solar System Collisions with Dense Interstellar Gas Clouds and Radiocarbon Traces of Periods with “Abnormally Low” Solar Modulation of Cosmic Rays
The causes of a sharp increase in the radiocarbon content in the Earth’s atmosphere for periods with abnormally low solar modulation of galactic cosmic rays (GCRs) are considered. It is shown that… Expand
