In the last 3000 yr, one significant and rapid increase in the concentration of 14 Ci n tree rings was observed; it corresponds to a γ -ray energy input of 7 × 10 24 erg at Earth within up to one year in AD 774/5. A normal supernova and a solar or stellar flare are unlikely as cause, so that the source remained unknown. Here, we show that a short gamma-ray burst (GRB) in our Galaxy is consistent with all observables: such an event is sufficiently short and provides the necessary energy in the… Expand

AD 775 Pulse of Cosmogenic Radionuclides Production as Imprint of a Galactic Gamma-Ray Burst
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… Expand
A solar super‐flare as cause for the 14C variation in AD 774/5?
We present further considerations regarding the strong 14C variation in AD 774/5. For its cause, either a solar super-flare or a short gamma-ray burst were suggested. We show that all kinds of… Expand
Gamma-ray bursts and the production of cosmogenic radionuclides in the Earth’s atmosphere
An explanation is offered for the impulsive increase in the concentration of cosmogenic radiocarbon in annual tree rings (Δ14C ∼ 12‰) from AD ≃775. A possible cause of such an increase could be the… 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
Reconstruction of cosmic-ray intensity in the past from measurements of radiocarbon in tree rings
Measurements of cosmogenic nuclides, which are radioisotopes produced by cosmic rays, can provide important information regarding extraterrestrial high-energy events. Until now, C in tree rings as… 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 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
“Isotopic footprints” of gamma-ray and proton events and anomalous signal in radiocarbon in 775 AD
The production of the cosmogenic radionuclides 14C, 10Be, and 36Cl in the Earth’s atmosphere under the action of powerful impulsive proton and gamma-ray events (superpowerful solar flares and… Expand
CAN THE 14C PRODUCTION IN 1055 CE BE AFFECTED BY SN1054?
ABSTRACT Annually resolved radiocarbon (14C) measurements on tree rings led to the discovery of abrupt variations in 14C production attributed to large solar flares. We present new results of annual… Expand
Supernovae and Single-Year Anomalies in the Atmospheric Radiocarbon Record
Abstract Single-year spikes in radiocarbon production are caused by intense bursts of radiation from space. Supernovae emit both high-energy particle and electromagnetic radiation, but it is the… Expand
