The magnetized Galactic ISM has become a main hindrance in the analysis of cosmological data. Galactic foregrounds are an issue in different observational contexts for the CMB, the HI 21cm signal from the EoR, line intensity mapping and lensing surveys. Galactic magnetic fields also upset the identification of sources of ultra-high energy cosmic rays and the measurement of extragalactic magnetic fields. In each context, cosmology is tied to Galactic astrophysics, and from a methodological point of view, to mathematics, because novel methods are required to model and reproduce the statistical properties of Galactic foregrounds and account for their complexity in the statistical inference of cosmological parameters.

The meeting aims at bringing together scientists from Cosmology, Galactic Astrophysics and Mathematics for cross-fertilization. These three themes will be developed in parallel along the week in the context of CMB, large scale structure, EoR, cosmic magnetism and cosmic-ray science and experiments.

More to come ... 


The meeting will take place on the 11-15 May 2020, in the city of Lattes, close to Montpellier, in the South of France.

Lattes is situated at 10 km from the Méditerranée sea, at the border of the Camargue Natural Park.
