The Link Between the Local Bubble and Radioisotopic Signatures on Earth
Jenny Feige, Dieter Breitschwerdt, Anton Wallner +15
Traces of 2-3 Myr old 60Fe were recently discovered in a manganese crust and in lunar samples. We have found that this signal is extended in time and is present in globally distrib…
11Be(beta-p), a quasi-free neutron decay?
K. Riisager, O. Forstner, M. J. G. Borge +18
We have observed beta-delayed proton emission from the neutron-rich nucleus 11Be by analysing a sample collected at the ISOLDE facility at CERN with accelerator mass spectrometry (…
AMS measurements of cosmogenic and supernova-ejected radionuclides in deep-sea sediment cores
J. Feige, A. Wallner, L. K. Fifield +6
Samples of two deep-sea sediment cores from the Indian Ocean are analyzed with accelerator mass spectrometry (AMS) to search for traces of recent supernova activity around 2 Myr ag…
The Search for Supernova-produced Radionuclides in Terrestrial Deep-sea Archives
Jenny Feige, Anton Wallner, Stephan R. Winkler +5
An enhanced concentration of 60Fe was found in a deep ocean's crust in 2004 in a layer corresponding to an age of ~2 Myr. The confirmation of this signal in terrestrial archives as…
