Mexico School: "Galactic Dynamics in the Times of Gaia and other Great Surveys"
Here is the first announcement of the School on Galactic Dynamics we
commented in our last ITN meeting in Bourdeaux. We have designed it to
have the same format as the Besançon School but now well focussed on
galactic dynamics. We think the school will be very interesting for all
of you so do not hesitate to contact us for any question.

We are pleased to announce a school on Galactic Dynamics
methods and techniques in the times of Gaia and large surveys,
to be held at the campus of UNAM in Mexico City, Mexico.
This is a school geared toward graduate students interested in
learning about modern approaches to Galactic Dynamics that
will be relevant in the era of Gaia.
------------ MOTIVATION ------------
Up to now our knowledge of the dynamics of our Galaxy has been limited
to a large extent to studies of the Solar Neighborhood and along a few
selected directions in the sky, which overall, represent a minuscle
of the stellar content and extent of the Galaxy. This has lead to the
of idealized dynamical models fitted to the few observations we have,
and their extrapolation to fill in the Glaxy's "terra incognita".
However, the advent of large scale surveys of the stellar content of
Galaxy, promises to revolutionize our knowledge of our Galaxy. The
Gaia spatial astrometric mission, to be launched at the end of this
in particular, promises a vast trove of information never before
because of its coverage, extent, homogeneity and precision: full
information for about a thousand million stars down to magnitude (G)
and even some spectral information for the brightest subset (down to
Such enormous database opens up new and exciting possibilities in the
of the structure of our Galaxy in general, and in that of the dynamics
of our Galaxy
in particular. The detailed phase space information for a significant
of stars in the Galaxy brings new possibilities in the modeling of the
The basic dynamical unit of collisionless systems like our Galaxy are
particles in phase space, but orbits. Methods to build these systems,
like the original Schwarzschild method, or more recently "made to
methods make evident this important role for orbits. Fourier methods
allow us to classify orbits in vast numbers and differentiate regular
irregular motion. Torus construction methods allow a complete
of systems shaped by regular orbits in 3-D action space, rather than
6-D phase space, retaining the essence of the dynamics of the system.
Advances in computational power and in the sophistication of numerical
allow us to follow vast number of particles in model potentials (test
simulations) and self-consistently (N-body simulations). In particular,
simulations, collisionality has been reduced to the point where orbit
is possible. Complementing all of these, powerful numerical tools have
developed to create mock catalogues of large scale surveys. In the case
Gaia, ithere are several codes that are being developed that permit the
construction of very realistic Gaia mock catalogues. These tools will
to explore "what if" situations and to confront observations with
into account the unavoidable bias and random observation errors.
Most of these methods, techniques and tools, do not form part (yet) of
standard graduate course in Galactic Dynamics, as they have been
or ar still being developed. However, they are very likely to have a
relevance in the dynamical sutdies of our Galaxy in the Gaia era.
------------ GOAL ------------
It is the goal of this school to introduce students to some of these
techniques and tools to do research in the dynamics and structure of
No previous experience in these topics is needed, but a base knowledge
Galactic Dynamics is required. This will be a "hands-on" school, where
lectures will be combined with computer labs to work out exercises that
illustrate the topics covered during the lectures. At the end, the
develop small projects where they can incorporate what they have
------------ PROGRAMME ------------
The school will consist of morning lectures and afternoon computer lab
The lecturers will present their material in a coordinated way,
the basic concepts behind the methods, techniques and tools covered
in the school. The lecture sessions will be split in short 45-minute
with plenty of time for the students to interact with the lecturers.
the afternoon sessions, the lecturers will introduce numerical
designed to illustrate in a "hands-on" fashion the material covered in
the lectures. Towards the middle of the school, the students are
to choose, or propose a project to develop. The last day of the school
be in a "simposium" format, with the teams of students presenting their
The topics covered will be:
* Introduction to Gaia mock catalogues
* Basic Hamitlonian theory
* Chaos vs. regularity: How to classify an orbit
* Torus construction methods
* Constraining the gavitational potential of the Galaxy
* Dynamical effects of the non-axial components of the Galaxy
* N-body modeling of the Milky Way disc
* SPH modeling of the Milky Way disc
A core of databases, codes and numerical tools will be available to
download by the students prior to the start of the school. This is so
that the students can install and run verification examples to make
sure they have everything ready when they arrive for the school.
Every student is expected to bring his/her own laptop computer
with all the numerical tools that will be indicated later on. Free
WiFi with access to the internet will be provided in the classroom
and all work areas.
The school runs for 10 days, so that the students have time to
develop their projects.

------------ VENUE ------------
The school will take place within tha main campus of the "Universidad
Nacional Autónoma de Mexico" (UNAM) in the south of Mexico city.
Specifically, it will be held at "Universum", a modern science museum
that belongs to UNAM. This is a very interesting part of Mexico city,
close to many areas of interest, including "Cuicuilco", the oldest
precolumbian village in the valley of Mexico, that was buried by the
of a volcaninc eruption.
------------ REGISTRATION ------------
40 participants will be selected to attend the school.
Applications are accepted until August 31st, 2013.
A first list of accepted participants will be published in the
page of the event by mid August. A second, and final list of accepted
participants, will be published by mid September.
Application forms should be completed on-line
via our web-page: http://www.astroscu.unam.mx/gaiaschoolmex/
------------ SCHOOL FEE ------------
A registration fee of $100.00 U.S. dollars will be charged to cover the
of the use of the facilities, coffee breaks and various support and
------------ FINANCIAL SUPPORT ------------
Some financial support is available that ranges from a school fee
to help with lodging and food costs, or even in some extraordinary
travel costs. Please indicate in the registration form if you need
All financial support requests should be accompanied by a letter from
student advisor supporting the case and explaining the reasons for the
