    • Keith Olive (U. of Minnesota) gave a 30 min. talk reviewing theoretical aspects on the variation of fundamental constants. In particular, the relation between the fundamental quantities, the model dependence on how they may vary, and finally, an interpretation of several experimental results focused on the test of the fine structure constant.

The path would be to analyse objects under three theoretical levels. Then, we would aim for a global results representation of all (selected) objects. Hence, for starters, a database will be generated with as many as possible analysed systems, including the obtained constraint and associated error, the method used to this purpose, redshift and coordinates of the object, source, etc. After/during the data gathering we will establish a selection criteria and keep only the "trusted" systems. This database will be living and updatable on our website.
    • Valerio described his proposal for IRAM. For the moment, it consists on 84 sources picked from Planck's 15th publication, with known redshifts, and among which 15% have detected molecular absorptions. Patrick will suggest a list of other sources worth to be observed. The deadline is on March 15th.
    • Finally, the wikipage was discussed. Philippe mounted the wiki, and Valerio has started writing a bit on it. We're all waiting for the link! This wiki will be public, and a private counterpart will be created for
      internal matters. It was suggested to use these tools to the database discussed above.

  • 19/01/2012:
    • the members of the project presented to each others;
    • discussed past and present projects;
    • defined some guidelines for upcoming common papers.

Today we held the second Vacoul meeting at IAP's room 281. We were all
present but Pasquier.

Keith Olive (U. of Minnesota) gave a 30 min. talk reviewing theoretical
aspects on the variation of fundamental constants. In particular, the
relation between the fundamental quantities, the model dependence on how
they may vary, and finally, an interpretation of several experimental
results focused on the test of the fine structure constant.

After a useful discussion about these topics, Jean-Philippe presented the
"VACOUL" document, inwhich he draws a line on what we should prepare as a
group for astrophysical limits on the variation of constants. The path
would be to analyse objects under three theoretical levels. Then, we would
aim for a global results representation of all (selected) objects. Hence,
for starters, a database will be generated with as many as possible
analysed systems, including the obtained constraint and associated error,
the method used to this purpose, redshift and coordinates of the object,
source, etc. After/during the data gathering we will establish a selection
criteria and keep only the "trusted" systems. This database will be living
and updatable on our website.

Valerio described his proposal for ALMA. For the moment, it consists on 84
sources picked from Planck's 15th publication, with known redshifts, and
among which 15% have detected molecular absorptions. Patrick will suggest
a list of other sources worth to be observed. The deadline is on March
15th.

Finally, the wikipage was discussed. Philippe mounted the wiki, and
Valerio has started writing a bit on it. We're all waiting for the link!
This wiki will be public, and a private counterpart will be created for
internal matters. It was suggested to use these tools to the database
discussed above.
