DREAMS, the DREsden AMS-facility, is performing routine accelerator mass spectrometry of
10 Be, 26 Al, 36 Cl, 41 Ca, and 129 I for a wide range of applications. All DREAMS-data is …

A dying massive star ends in a supernova explosion ejecting a large fraction of its mass into
the interstellar medium. If this happens nearby, part of the ejecta might end on Solar System …

Earth is constantly bombarded with extraterrestrial dust containing invaluable information
about extraterrestrial processes, such as structure formation by stellar explosions or …

The arid to semi-arid climate of northern African countries is an asset for the preservation of
meteorites and impact structures. The Sahara, the largest hot desert in the world, is …

We have investigated silicate emulsions in impact glasses and impact melt rocks from the
Wabar (Saudi Arabia), Kamil (Egypt), Barringer (USA), and Tenoumer (Mauritania) impact …

In small meteorite impacts, the projectile may survive through fragmentation; in addition, it
may melt, and chemically and physically interact with both shocked and melted target rocks …

The discovery of live 60 Fe in a deep-sea crust with proposed interstellar origin followed by
evidence for elevated interplanetary 3 He in the same crust raised the question on how to …

The Twannberg iron meteorite is one out of only six members of the group IIG. The
combined noble gas and radionuclide data obtained in this new systematic study indicate …

We measured specific activities of the long‐lived cosmogenic radionuclides 60Fe in 28 iron
meteorites and 53Mn in 41 iron meteorites. Accelerator mass spectrometry was applied at …

We report on the microscopic impactor debris around Kamil crater (45 m in diameter, Egypt)
collected during our 2010 geophysical expedition. The hypervelocity impact of Gebel Kamil …
