A census of cool core galaxy clusters in IllustrisTNG
David J. Barnes, Mark Vogelsberger, Rahul Kannan +10
The thermodynamic structure of hot gas in galaxy clusters is sensitive to astrophysical processes and typically difficult to model with galaxy formation simulations. We explore the…
The uniformity and time-invariance of the intra-cluster metal distribution in galaxy clusters from the IllustrisTNG simulations
Mark Vogelsberger, Federico Marinacci, Paul Torrey +8
The distribution of metals in the intra-cluster medium encodes important information about the enrichment history and formation of galaxy clusters. Here we explore the metal conten…
First results from the IllustrisTNG simulations: radio haloes and magnetic fields
Federico Marinacci, Mark Vogelsberger, Rüdiger Pakmor +8
We introduce the IllustrisTNG project, a new suite of cosmological magnetohydrodynamical simulations performed with the moving-mesh code AREPO employing an updated Illustris galaxy…
Galaxy Formation with BECDM: I. Turbulence and relaxation of idealised haloes
Philip Mocz, Mark Vogelsberger, Victor Robles +4
We present a theoretical analysis of some unexplored aspects of relaxed Bose-Einstein condensate dark matter (BECDM) haloes. This type of ultralight bosonic scalar field dark matte…
Offsets between member galaxies and dark matter in clusters: a test with the Illustris simulation
Karen Y. Ng, Annalisa Pillepich, David Wittman +3
Dark matter with a non-zero self-interacting cross section () has been posited as a solution to a number of outstanding astrophysical mysteries. Many studies of mergi…
