Monday afternoon: Cosmological simulations
- Christoph Pfrommer (AIP Potsdam)
The outskirts of galaxy clusters is one of the new frontiers at the crossroads of cosmology and astrophysics, promising to serve as a powerful laboratory for studying the cosmological growth of structure as well as rich gastrophysics in the infall regions around the most massive dark matter halos. In this talk, I will discuss recent advances in our understanding of the physics of the...
With the cosmological magneto-hydrodynamical simulations IllustrisTNG (https://www.tng-project.org/), we are putting together ever more quantitative and plausible evidences as to the role that feedback from SMBHs can have in determining the physical properties of the gas in and around galaxies, all the way up to the mass scale of galaxy clusters. Powerful energy injections originating from the...
I will discuss highlights from our recent simulation results, focusing on the interplay of supermassive black hole feedback and the halo gas of massive groups and clusters. I will touch on (i) baryon redistribution and clusters as closed boxes, (ii) turbulence and kinematics in the ICM due to cosmological assembly versus feedback, (iii) the virial shock and the outskirts/IGM interface, (iv)...
Current observations reveal that supermassive black holes (SMBHs) are nearly ubiquitous in massive galaxies in the local Universe. They are thought to be the central engines powering the feedback from active galactic nuclei (AGN), which is a standard ingredient in current cosmological simulations of galaxies and clusters of galaxies. In this talk I will present our recent results on the...
We present a suite of 13 triple merger simulations using the FLASH hydrodynamic + N-body code which we use to derive a means of distinguishing a multi-merger system from a simple binary merger system using sloshing cold fronts. Our simulations explore different trajectories of a 1:10:10 triple merger. In particular we focus on the growth rate of sloshing cold fronts and the potential impact...
The Perseus Cluster is a well-studied system in the X-rays, presenting spiral-shaped cold fronts which extend to large radii. These features are believed to be caused by the sloshing motion of the gas after the passage of a subcluster. We present simulations of the formation of sloshing cold fronts in Perseus using the AREPO magnetohydrodynamics code, with the aim of reproducing the positions...
