Positive feedback at the disc-halo interface
Alexander Hobbs, Robert Feldmann
The flat star formation (SF) history of the Milky Way (MW) requires gas in the Galactic disc to be replenished, most likely from a reservoir outside the Galaxy. Such a replenishmen…
Spurious Small-Scale Structure & Discreteness-Driven Relaxation in Cosmological Simulations
Chris Power, Aaron S. G. Robotham, Danail Obreschkow +2
There is strong evidence that cosmological N-body simulations dominated by Warm Dark Matter (WDM) contain spurious or unphysical haloes, most readily apparent as regularly spaced l…
nIFTy Galaxy Cluster simulations IV: Quantifying the Influence of Baryons on Halo Properties
Weiguang Cui, Chris Power, Alexander Knebe +21
Building on the initial results of the nIFTy simulated galaxy cluster comparison, we compare and contrast the impact of baryonic physics with a single massive galaxy cluster, run w…
nIFTy galaxy cluster simulations I: dark matter & non-radiative models
Federico Sembolini, Gustavo Yepes, Frazer R. Pearce +24
We have simulated the formation of a galaxy cluster in a CDM universe using twelve different codes modeling only gravity and non-radiative hydrodynamics (\art, \arepo, \hydra\ a…
Novel Adaptive softening for collisionless N-body simulations: Eliminating spurious halos
Alexander Hobbs, Justin Read, Oscar Agertz +2
We describe a NOVel form of Adaptive softening (NovA) for collisionless -body simulations, implemented in the Ramses adaptive mesh refinement code. We introduce a refinement cri…
Growing galaxies via superbubble-driven accretion flows
Alexander Hobbs, Justin Read, Andrina Nicola
We use a suite a cooling halo simulations to study a new mechanism for rapid accretion of hot halo gas onto star-forming galaxies. Correlated supernovae events create converging 's…
