Subject: Workshop on the SZ Effect & ALMA: first annoucement

Dear Colleagues, 

In the context of the European network RadioNet and of the ALMA
project, we are organizing a workshop with the title 'SZ Effect and
ALMA'. 

The workshop will be held on April 7 and 8, 2005 at the Institut
d'Astrophysique Spatiale in Orsay (Paris area), France. The format 
of the workshop will allow for open discussions around a few key
presentations and the expected attendance will be about 50
participants.

We would like to know if you are interested in attending this
workshop. Also if you would like to contribute with a short
presentation related to the workshop topic, could you please inform
us.  For your information, we have listed below the summary of the
aims and the expected outcomes of this workshop, as well as the
current list of key presentations.

If you are interested, please send a reply mail to both of us as soon
as possible. We will keep you further informed about practical details
by the end of january.
  
Also could you please circulate this annoucement to those you might
think could be interested in attending this workshop and who are not
part of this mailing list. Thank you in advance.

Looking forward to seeing you in Orsay, we wish you 
all the best for the New Year 2005. 

Nabila Aghanim & Pierre Cox

          'The SZ Effect and ALMA' 

      Institut d'Astrophysique Spatiale
           Universite de Paris-Sud
               Orsay (France) 


The aim of this workshop, which will be organized as part of the ALMA
Forum in RadioNet, is to gather specialists of the Sunyaev-Zel'dovich
(SZ) effect both with theoretical and observational backgrounds to
discuss the status of the field and the current and planned experiments,
in order to assess the role of ALMA in SZ studies. 

The goals of this workshop are: 

i) to start discussions on what will remain to be done on the SZ
   effect at the beginning of 2012 when ALMA will be fully operational.

ii) to investigate the importance of observations of the SZ effect at
    high-angular resolution.

iii) to define what are the key frequency bands for SZ studies in the
     mm/submm windows, in particular, are there crucial bands which 
     are not in the baseline project?


The workshop will be organized around a few key presentations on the
subject and ample time will be devoted to open discussions. It is the
wish of the organizers to produce a document based on the presentations 
and the conclusions of this workshop. This document could serve as a 
first reference for further considerations in the ALMA project.
