Workshop
"The SZ effect and ALMA"
Insitut d'Astrophysique Spatiale -
Orsay
7-8 april 05
In the context of the European network RadioNet and of the ALMA
project, we organized a workshop with the title 'SZ Effect and
ALMA'.
The workshop was held on April 7 and 8, 2005 at the Institut
d'Astrophysique Spatiale in Orsay (Paris area), France.
Aim of the meeting
The aim of this workshop, which was organized as part of the ALMA
Forum in RadioNet, was 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 was organized around a few key presentations on the
subject and ample time was 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.
