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…

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,…
