CAFFELattes — Cosmological analyses featuring Galactic foreground emission
11 mai 2020 - 15 mai 2020 • Montpellier, France
Résumé:
The magnetized Galactic interstellar medium has become a main hindrance in the analysis of cosmological data. Galactic foregrounds are an issue in different observational contexts for the Cosmic Microwave Background (CMB), the HI 21cm signal from the epoch of reionization (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.

08 jui 2020 - 12 jui 2020 • Chamonix, France
Résumé:
The Symposium will focus on computational methods applied to speed up and broaden the scope of scientific studies, such as finding trends from observational data, high performance computing, automated search algorithms, and model predictability. The meeting will bring together experts to discuss a palette of challenging informational and technical developments, including hardware and software but always focused on astronomical applications.

Dust2020 — The Rise of Metals and Dust in Galaxies through Cosmic Time
13 jul 2020 - 17 jul 2020 • Marseille, France
Organisateur:
Laboratoire d'Astrophysique de Marseille
Résumé:
Before the birth of the first generation of stars (population III), the universe contained essentially only hydrogen and helium atoms. But after these first stars ignited, they synthesized in their cores nuclei of atoms heavier and heavier (the rise of metals). Some of these atoms have formed grains of dust, which is now everywhere in the interstellar medium. Dust absorbs and diffuses ultraviolet radiation and optical light, which heats the dust particles that ultimately produce radiation that is re-emitted in the infrared. This process modifies our vision of galaxies and of the universe and has dominated the universe for several billion years (the rise of dust). In addition to the effects of reddening and obscuration, dust grains also play a crucial role in star formation and in the physics and chemistry of the interstellar medium, such as heating and cooling processes, gas dynamics, charge transfer and the formation of H2 molecules. It is therefore important to progress in understanding the history of the formation of heavy elements in the universe as well as the different phases of the duty cycle of dust and the variation of this cycle according to the environment and the cosmic times.

Celebrating Sydney Leach : from Molecular Photophysics to Astrobiology with Musical Interludes
22 sep 2020 - 25 sep 2020 • Orsay, France
Résumé:
As many of you know, Sydney Leach died on December 24th 2019, at the age of 95. He was active to the very end. Sydney was a pillar of modern chemical physics and, through his many and lasting contributions, has been a major influence in placing ‘photophysique moléculaire’ squarely on the map of post-war science. Many of us, hearing of the sad news of his death, immediately felt that a meeting to commemorate Sydney’s life-long contribution would be very appropriate. Such a meeting is planned for September 22nd-25th of this year, to take place at Orsay at the Institut des Sciences Moléculaires d’Orsay.

International School on The Interstellar Medium of Galaxies, from the Epoch of Reionization to the Milky Way
19 jul 2021 - 23 jul 2021 • Banyuls-sur-Mer, France
Résumé:
This international school will offer an overview of the observational constraints, the interpretative tools and the theoretical frameworks used for studying the interstellar medium in galaxies from the epoch of reionization to the Milky Way. Furthermore, it aims to build a synergy between the Galactic ISM and extragalactic communities. Time will be devoted to discussion between participants and lecturers, with the hope of kick-starting original projects.
