Models of rotating coronae
Mattia C. Sormani, Emanuele Sobacchi, Gabriele Pezzulli +2
Fitting equilibrium dynamical models to observational data is an essential step in understanding the structure of the gaseous hot haloes that surround our own and other galaxies. H…
The GALAH survey and Gaia DR2: dissecting the stellar disc's phase space by age, action, chemistry and location
Joss Bland-Hawthorn, Sanjib Sharma, Thor Tepper-Garcia +24
We use the second data releases of the ESA Gaia astrometric survey and the high-resolution GALAH spectroscopic survey to analyse the structure of our Galaxy's disc components. With…
The origin of the Gaia phase-plane spiral
James Binney, Ralph Schoenrich
A simple model is presented of the formation of the spiral the (z,v_z) phase plane of solar-neighbourhood stars that was recently discovered in Gaia data. The key is that the frequ…
Correlations between age, kinematics, and chemistry as seen by the RAVE survey
Jennifer Wojno, Georges Kordopatis, Matthias Steinmetz +20
We explore the connections between stellar age, chemistry, and kinematics across a Galactocentric distance of , using a sample of inte…
Revisiting relaxation in globular clusters
Chris Hamilton, Jean-Baptiste Fouvry, James Binney +1
The classical theory of cluster relaxation is unsatisfactory because it involves the Coulomb logarithm. The Balescu-Lenard (BL) equation provides a rigorous alternative that has no…
Action-based dynamical models of dwarf spheroidal galaxies: application to Fornax
Raffaele Pascale, Lorenzo Posti, Carlo Nipoti +1
We present new dynamical models of dwarf spheroidal galaxies (dSphs) in which both the stellar component and the dark halo are described by analytic distribution functions that dep…
