Quantifying Chaos in Models of the Solar Neighbourhood
Dalia Chakrabarty, Ioannis V. Sideris
{} {To quantify the amount of chaos that exists in the local phase space.} {A sample of orbits from four different models of the Solar neighbourhood phase space are analysed by a n…
Influence of Orbital Behaviour and Chaos on the Shape of Dark Matter Halos
Andrea V. Maccio', Ioannis Sideris, Marco Miranda +2
It has been shown that the dissipative gas infall during galaxy formation has the capability to modify the shape of dark matter halos. In this paper we perform the first detailed a…
Noise-Enhanced Parametric Resonance in Perturbed Galaxies
Ioannis V. Sideris, Henry E. Kandrup
This paper describes how parametric resonances associated with a galactic potential subjected to relatively low amplitude, strictly periodic time-dependent perturbations can be imp…
Supermassive Black Hole Binaries as Galactic Blenders
Henry E. Kandrup, Ioannis V. Sideris, Balsa Terzic +1
This paper focuses on the dynamical implications of close supermassive black hole binaries both as an example of resonant phase mixing and as a potential explanation of inversions…
Transient chaos and resonant phase mixing in violent relaxation
Henry E. Kandrup, Ileana M. Vass, Ioannis V. Sideris
This paper explores how orbits in a galactic potential can be impacted by large amplitude time-dependences of the form that one might associate with galaxy or halo formation or str…
Smooth potential chaos and N-body simulations
Henry E. Kandrup, Ioannis V. Sideris
Integrations in fixed N-body realisations of smooth density distributions corresponding to a chaotic galactic potential can be used to derive reliable estimates of the largest (fin…
