RABBITS IV: Stellar feedback and SMBH merging time-scales in the sub-Milky Way mass regime
Ruby J. Wright, Roosa Heiskanen, Shihong Liao +5
The authors run high‑resolution galaxy merger simulations to examine how the strength of stellar feedback influences the delay between galaxy coalescence and the merger of supermas…

Stellar flares cannot explain the Galactic 511 keV emission
Saurabh Mittal, Thomas Siegert, Francesca Calore +12
The authors assess whether stellar flares can produce enough positrons to explain the Milky Way’s 511 keV annihilation line and conclude that flares fall short by several orders of…

Connecting The Hierarchically Merging Binary Black Hole Population To Their Host Galaxies
Jordan Moncrieff, Fiona Panther
The detection of gravitational waves from merging black holes with masses suggests that some proportion of black hole binary systems form hierarchi…
