Acceleration and Transport of the Unstable Cosmic-ray Isotope Fe in Supernova-Enriched Environments
Xin-Yue Shi, Martin Pohl, Michael M. Schulreich
The unstable isotope Fe, with a half-life of 2.6 million years, is produced primarily in supernova explosions. The observed presence of Fe in cosmic rays and its dete…
Tidal disruption events as the origin of the eROSITA and Fermi bubbles
Tassilo Scheffler, Michael M. Schulreich, David P. P. R. Schurer +1
Context: The recently discovered spherical eROSITA bubbles arise up to a latitude of 80°-85°in the X-ray regime of the Milky Way halo. Similar to the -ray Fermi bubbles, th…
Gamma-ray line emission from the Local Bubble
Thomas Siegert, Michael M. Schulreich, Niklas Bauer +3
Deep-sea archives that include intermediate-lived radioactive particles suggest the occurrence of several recent supernovae inside the present-day volume of the…
The time-dependent Rayleigh-Taylor instability in interstellar shells and supershells, including the eROSITA bubbles
Michael Mathias Schulreich, Dieter Breitschwerdt
The Rayleigh-Taylor (RT) instability is omnipresent in the physics of inversely density-stratified fluids subject to effective gravitational acceleration. In astrophysics, a steep…
A Way Out of the Bubble Trouble? - Upon Reconstructing the Origin of the Local Bubble and Loop I via Radioisotopic Signatures on Earth
Michael Mathias Schulreich, Dieter Breitschwerdt, Jenny Feige +1
Deep-sea archives all over the world show an enhanced concentration of the radionuclide Fe, isolated in layers dating from about 2.2 Myr ago. Since this comparatively long-l…
Numerical studies on the link between radioisotopic signatures on Earth and the formation of the Local Bubble. I. 60Fe transport to the solar system by turbulent mixing of ejecta from nearby supernovae into a locally homogeneous ISM
Michael Mathias Schulreich, Dieter Breitschwerdt, Jenny Feige +1
The discovery of radionuclides like 60Fe with half-lives of million years in deep-sea crusts and sediments offers the unique possibility to date and locate nearby supernovae. We wa…
