     Guillermo-Haro International Advanced School:
 "A Pan-Chromatic View on Clusters of Galaxies and
              Large-Scale Structure"

               INAOE, Tonanzintla-Mexico
                June 27 - July 8, 2005

*****************************************************

 MOTIVATION
 ----------
The study of clusters of galaxies has developed significantly in recent 
years due to large dedicated spectroscopic and wide-field imaging surveys, 
covering X-ray to radio wavelengths, and the simultaneous advances in 
numerical astrophysics. It is therefore timely to update previous reviews 
on the physical nature of clusters and their evolution. This summer-school 
will provide the opportunity to disseminate the new results and methodologies 
in cluster research to senior graduate students and young post-docs training 
in multi-wavelength astrophysics and cosmology.

The advanced school will be restricted to ~100 participants selected from 
those that register before the final deadline of April 1st 2005.
The applicants should be familiar with modern extragalactic and observational 
cosmology research, and some of the topics covered by the Advanced School.

 PROGRAMME
 ---------
The main programme will consist of a total of ~50 hours of advanced lectures covering
 the following range of topics:

 * Structure formation theories: from initial perturbations
       to clusters and galaxies
 * The cluster - large-scale structure connection
 * Cluster internal dynamics I: gravo-thermal processes,
       violent relaxation, dynamical friction, tidal stripping
 * Cluster internal dynamics II: accretion, merging, ICM
 * Multi-wavelength properties & clusters Searches (Optical,
       IR, Radio, HI, X-ray)
 * Cluster N-body simulations
 * The Sunayev-Zel'dovich effect
 * Cluster lensing
 * Evolution of galaxy populations in clusters
 * Precision cosmology with clusters

 LECTURERS
 ---------
The advanced lecture material will be delivered by the following
experts:

    * Luis Aguilar
    * Mark Birkinshaw (TBC)
    * Dick Bond (TBC)
    * Stefano Borgani
    * George Djorgovski
    * Luigina Feretti
    * Carlos Frenk
    * Jaqueline van Gorkom
    * Christine Jones
    * Jean-Paul Kneib
    * Alvio Renzini
    * Craig Sarazin
    * Rien van de Weygaert

A more detailed programme of the individual lectures will be made 
available shortly on our web-page and in a future circular.

 VENUE
 -----
The advanced school is part of the annual international Guillermo Haro 
programme, which promotes advanced research through the organization of 
lecture series, workshops, and conferences at the Instituto Nacional de 
Astrofisica, Optica y Electronica in Tonanzintla - Puebla, Mexico.

 REGISTRATION
 --------------
About ~100 participants will be selected to attend the advanced school 
from those that register before the final deadline of April 1st 2005.
Registration can be completed on-line via our web-page:

 HOTEL INFORMATION
 ----------------------------------
Information regarding the accomodation during the advanced school will 
appear shortly in our web-page and in our next circular.

 PROCEEDINGS
 -----------
The lectures will be published before the end of 2005, either as part of the ASP 
Conference series, Springer Verlag Lecture Notes in Physics or by Kluwer Academic Press.

 CONFERENCE FEE
 --------------
The registration fee of 220 US dollars covers the cost of the published proceedings, 
the lunches and coffee-breaks.
