Increasing blackhole feedback induced quenching with anisotropic thermal conduction
Rahul Kannan, Mark Vogelsberger, Christoph Pfrommer +5
Feedback from central supermassive blackholes is often invoked to explain the low star formation rates in massive galaxies at the centers of galaxy clusters. However, the detailed…
Cosmic ray heating in cool core clusters - II. Self-regulation cycle and non-thermal emission
Svenja Jacob, Christoph Pfrommer
Self-regulated feedback by active galactic nuclei (AGNs) appears to be critical in balancing radiative cooling of the low-entropy gas at the centres of galaxy clusters and in regul…
Cosmic ray heating in cool core clusters - I. Diversity of steady state solutions
Svenja Jacob, Christoph Pfrommer
The absence of large cooling flows in cool core clusters appears to require self-regulated energy feedback by active galactic nuclei (AGNs) but the exact heating mechanism has not…
Cosmic ray-driven galactic winds: streaming or diffusion?
Joshua Wiener, Christoph Pfrommer, S. Peng Oh
Cosmic rays (CRs) have recently re-emerged as attractive candidates for mediating feedback in galaxies because of their long cooling timescales. They can have energy densities comp…
The role of cosmic ray pressure in accelerating galactic outflows
Christine M. Simpson, Ruediger Pakmor, Federico Marinacci +5
We study the formation of galactic outflows from supernova explosions (SNe) with the moving-mesh code AREPO in a stratified column of gas with a surface density similar to the Milk…
Galactic winds driven by isotropic and anisotropic cosmic ray diffusion in disk galaxies
Ruediger Pakmor, Christoph Pfrommer, Christine M. Simpson +1
The physics of cosmic rays (CR) is a promising candidate for explaining the driving of galactic winds and outflows. Recent galaxy formation simulations have demonstrated the need f…
