This working group (website here) is dedicated to raise awareness of new tools and methodology developed in the wider French community to do cosmology. The tools must be understood in a wide sense: it may be large software stack, online websites, or Mathematica© notebook.
This Working Group aims at sharing and helping the development of tools for which the needs are common to all the actors of the GDR.
It includes:
- tools that are oriented toward the predictions of cosmological observables (including non-linearities) and their relative theoretical systematic uncertainties such 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 higher order statistics;
- mathematical methods for inference such as the one based on MCMC, Machine Learning, and minimizer;
- production of validation data, such as mock galaxy catalog, mock CMB maps;
- tools for symbolic-based computation in the cosmological context.
This session is dedicated particularly to the use of Photometric redshift estimator (such as LePhare), Strong 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)
- Raphael Gavazzi (Strong lensing)
- Guilhem Lavaux (Manticore)
The meeting will occur at the LAM:
Laboratoire d’Astrophysique de Marseille
UMR7326
Pôle de l’Étoile Site de Château-Gombert
38, rue Frédéric Joliot-Curie
13388 Marseille CEDEX 13 FRANCE
To reach it from the central train station: subway line 1, stop at the terminus La Rose and then the bus B3 (2 stops).
Please note that the present timetable is preliminary and slots may be swapped depending on external constraints.
