DESCRIPTION:This working group (website here) is dedicated to raise awaren
 ess of new tools and methodology developed in the wider French community t
 o do cosmology. The tools must be understood in a wide sense: it may be la
 rge software stack\, online websites\, or Mathematica© notebook.This Work
 ing Group aims at sharing and helping the development of tools for which t
 he needs are common to all the actors of the GDR.It includes:tools that ar
 e oriented toward the predictions of cosmological observables (including n
 on-linearities) and their relative theoretical systematic uncertainties su
 ch as Boltzmann solvers\, numerical simulations\, approximate methods for 
 the non-linear evolution\, and forward modeling\,development of estimators
  for data analysis which are for example based on power spectra\, and high
 er order statistics\;mathematical methods for inference such as the one ba
 sed on MCMC\, Machine Learning\, and minimizer\;production of validation d
 ata\, such as mock galaxy catalog\, mock CMB maps\;tools for symbolic-base
 d computation in the cosmological context.This session is dedicated partic
 ularly to the use of Photometric redshift estimator (such as LePhare)\, St
 rong lensing image synthesis/analysis\, and the use of Manticore (https://
 cosmictwin.org) data products for cross-correlation analysis.Lectures will
  be provided by:Olivier Ilbert and Marie Treyer  (Photometric redshift\, 
 Hands on Le Phare)Raphael Gavazzi and Marceau Limousin (Strong lensing)Gui
 lhem Lavaux (Manticore https://cosmictwin.org\, Field Level Inference / Cr
 oss-correlation with CMB/SNe distances)  We can support the venue of sev
 eral young researchers: please contact the organizing committee. Also coff
 ee breaks/workshop dinner are included and registration is free (thanks to
  the support by the GDR Cophy).The meeting will occur at the LAM:Laboratoi

 To reach it from the central train station: subway  line 1\, stop at the 
 terminus La Rose and then the bus B3 (2 stops).The workshop will take plac
 e at LAM Amphitheater on ground floor. Coffee breaks will be at LAM\, lun
 ches near LAM and dinner on Monday at Novotel Hotel (near Pharo)Please not
 e that the present timetable is preliminary and slots may be swapped depen
 ding on external constraints.LOC:R.Gavazzi\, M.Limousin\, M.Treyer\, O.Ilb
