Shock-Driven Periodic Variability in a Low-Mass-Ratio Supermassive Black Hole Binary
K. Whitley, A. Kuznetsova, K. Gültekin +1
We investigate the time-varying electromagnetic emission of a low-mass-ratio supermassive black hole binary (SMBHB) embedded in a circumprimary disk, with a particular interest in…
On the Origin of the Ancient, Large-Scale Cold Front in the Perseus Cluster of Galaxies
Elena Bellomi, John ZuHone, Rainer Weinberger +4
The intracluster medium of the Perseus Cluster exhibits spiral-shaped X-ray surface brightness discontinuities known as ``cold fronts'', which simulations indicate are caused by th…
Cosmic ray feedback in galaxies and galaxy clusters -- A pedagogical introduction and a topical review of the acceleration, transport, observables, and dynamical impact of cosmic rays
Mateusz Ruszkowski, Christoph Pfrommer
Understanding the physical mechanisms that control galaxy formation is a fundamental challenge in contemporary astrophysics. Recent advances in the field of astrophysical feedback…
