Bar-halo interaction: the role of orbital anisotropy
Paula Gherghinescu, Francesca Fragkoudi, Alis Deason
We investigate the dynamical response of dispersion-dominated halo populations to a rotating galactic bar, focusing on how the underlying halo phase space distribution function (DF…
Stirring Things Up: Bar-induced substructures in the stellar halo of a cosmological Milky Way analogue
Thomas Tomlinson, Francesca Fragkoudi, Andreia Carrillo +8
The stellar halo of the Milky Way contains the remnants of past accretion events, which could be detectable as substructures in the classical integrals of motion space, such as ene…
How much can we learn from resolved stellar kinematics of galactic haloes using action-based dynamical models?
Paula Gherghinescu, Eugene Vasiliev, Payel Das +1
Dynamical models are used to study dark matter (DM) in galaxies, how galaxies assemble through mergers, and to test galaxy formation models. Despite its widespread use, there has b…
Action-based dynamical models of M31-like galaxies
Paula Gherghinescu, Payel Das, Robert J. J. Grand +1
In this work, we present an action-based dynamical equilibrium model to constrain the phase-space distribution of stars in the stellar halo, present-day dark matter distribution, a…
