PARC — PHYSICS and ASTROPHYSICS of COSMIC RAYS
25 nov 2019 - 30 nov 2019 • Saint Michel l'Observatoire, France
Résumé:
The school offers a broad training program including: - the theoretical aspects of the acceleration and propagation of non-thermal particles, - direct and indirect measurements of cosmic rays, - the role of cosmic rays in astrophysics and its place in multi-messenger astronomy and the understanding of dark matter, - two practical sessions on propagation models and their comparison to direct measurements, and data analysis with the future Cherenkov Telescope Array.

The school is aimed primarily at students and young researchers wishing to build or perfect their knowledge of cosmic rays. Financial support is available for PhD students and CNRS staff can benefit from a support for the stay.

CoSyne — Cosmological Synergies in the upcoming decade
09 dec 2019 - 12 dec 2019 • Paris, France
Résumé:
The coming decade of astrophysics and cosmology will be driven by a large number of missions which will explore the cosmos observing the sky through e.g. electromagnetic waves, cosmic and gamma rays, gravitational waves and neutrinos. This will make possible a multi-messenger approach, capitalizing on multiple probes that capture phenomena of the Universe in different observational channels over a large range of redshifts and will open the opportunity to study the synergies between different experiments.

The conference will bring researchers working on theoretical aspects, statistical methods and observational cosmology and will discuss the new directions of fundamental physics and cosmological mysteries which can be addressed from these multi-messenger multi-frequency probes. Along with probing the fundamental aspect of gravity, nature of dark energy, properties of dark matter, primordial gravitational waves, neutrino masses and hierarchy, next-generation missions will also be powerful probes to learn about the astrophysical aspects such as the population of black holes, properties of first stars, reionization history of the Universe, galaxy evolution and the interplay between cosmological and astrophysical effects. The meeting will also discuss future statistical tools and machine learning techniques which will be required to make robust measurements from the data which will be available from the upcoming missions on astrophysical gravitational waves, cosmic microwave background, large scale structure, line intensity mapping, supernovae and many others.

Sujets:
Cosmic microwave background, gravitational waves, large scale structure, line intensity mapping, standard candles.

The Interstellar Shocks School
22 mar 2020 - 27 mar 2020 • Les Houches, France
Organisateur:
Physics school of Les Houches
Résumé:
The Interstellar Shocks School is a one-week session in the Physics school of Les Houches. Its goal is to provide a comprehensive view of the physics and chemistry of interstellar shocks and detailed presentation of the multiple impacts they have on their close environments (i.e. energetics, star formation, cosmic ray acceleration). The session will include lectures dedicated to the physical, thermal, and chemical processes at play in shocks, observations of shocks in galactic and extragalactic sources, as well as state-of-the-art models, and lab experiments. Those lectures will be completed with tutorial and hands-on sessions so that all participants can get familiar with publicly available codes simulating the propagation of interstellar shock waves.

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.

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.
