Postpone of the CAFFE LATTES conference

Thursday the 12th of March 2020,

Dear participants of the CAFFE LATTES conference,

Thanks to your interesting and diverse contributions, we were shaping an exciting scientific program and were very much looking forward to the meeting. Unfortunately, in light of the global spread of COVID-19, we had a discussion among the LOC on Monday to decide what to do with respect to the epidemia. The recent evolution in France and around the world is very worrisome and we think that we need to cancel the meeting. This is a difficult decision that we need to take early enough before you are engaged financially.

We will reschedule the CAFFE LATTES conference in 2021. We are considering two possible locations, Paris at the Ecole Normale Supérieure and the South of France again. We will keep you informed on our plans.

We appreciate your contribution to the scientific program of the CAFFE LATTES conference, and hope that you will be available to participate next year. 

We are looking forward for meeting you in 2021.

Vincent Guillet, François Boulanger, Jonathan Aumont and Alexandre Marcowith, for the CAFFE LATTES conference

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 a hundred 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.
