Modelling the Milky Way in the Era of Gaia - JD5 programme
 

The challenge




Stars I Star counts, radial velocities, proper motions, metallicities and ages Annie Robin (France)
Stars II Large-scale non-equilibrium structures Vasily Belokurov (UK)
Stars III Non-equilibrium dynamics and radial migration in the disc Alice Quillen (USA)
Populations Star-formation histories, metallicity distributions and luminosity functions of disk, bulge & halo Rosie Wyse (USA)
ISM I Measures of ISM density (absorption, emission at various frequencies, polarization, Faraday rotation, dust to gas ratio) ??
ISM II Gas dynamics: motions driven by bar and spiral structure; impact on large-scale gas distribution (x2 ring, molecular ring or arms?); validity of kinematical distances Lia Athanassoula (France)
Mass distribution Exploiting horizontal and vertical dynamics of disc, dynamics of halo structures and satellites Amina Helmi (Netherlands)

Methods

Schwarzschild Introduction to orbit-superposition models. How do we fit such a model to a catalogue? Roeland van der Marel (USA)
Tori Torus modelling as an extension of Schwarzschild; respects in which it supercedes Schwarzschild James Binney (UK)
N-body In what detail can we represent the MW in a conventional N-body model? Victor Debattista (UK)
M2M To what extent does M2M overcome limitations of conventional N-body? Ortwin Gerhard (Germany)
Projection Projecting models into the observational domain; can we develop common tools for this? what would be the standard interfaces? Herwig Dejonge (Belgium)
Dust-fitting Given the Gaia catalogue, an NIR catalogue (VHS?) and a dynamical model, how to build a dust model? Jacques Lepine (Brazil)
Fitting How to optimise complex models? Will the computational scale be worryingly large? Prasenjit Saha (Switzerland)
Summary   Ken Freeman (Australia)
