The universal thickness of mid-infrared bubbles
Michael M. Schulreich, A. Beate C. Patzer
Several hundred ring-like structures seen at m in the Spitzer GLIMPSE surveys share a uniform morphology: the shell thickness is a nearly constant fraction of the outer ra…
Gas accretion onto the Milky Way: high-velocity cloud survival and the revival of the terminal-velocity paradigm
Michael M. Schulreich, Dieter Breitschwerdt, Jürgen Kerp
The terminal-velocity paradigm has long been used to interpret the motion and infer the distances of HVCs accreting onto the Milky Way, yet its validity under realistic Galactic co…
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…
Numerical studies on the link between radioisotopic signatures on Earth and the formation of the Local Bubble. II. Advanced modeling of interstellar 26Al, 53Mn, 60Fe, and 244Pu influxes as traces of past supernovae in the solar neighborhood
Michael Mathias Schulreich, Jenny Feige, Dieter Breitschwerdt
Measurements of long-lived radioisotopes provide a means, completely independent of other observational channels, to draw conclusions about near-Earth supernovae (SNe) and thus 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…
Near-Earth Supernova Explosions: Evidence, Implications, and Opportunities
Brian D. Fields, John R. Ellis, Walter R. Binns +36
There is now solid experimental evidence of at least one supernova explosion within 100 pc of Earth within the last few million years, from measurements of the short-lived isotope…
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…
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…
Astrophysical bow shocks: An analytical solution for the hypersonic blunt body problem in the intergalactic medium
Michael Mathias Schulreich, Dieter Breitschwerdt
Aims: Bow shock waves are a common feature of groups and clusters of galaxies since they are generated as a result of supersonic motion of galaxies through the intergalactic medium…
