Le laboratoire héberge régulièrement des colloques et ateliers focalisant sur un sujet particulier
parmi les thématiques et projets du laboratoire.
Ces rencontres durent quelques jours et sont destinées à une audience professionnelle.
"Galaxies in Absorption" is the 6th in a series of workshops intented to explore all aspects of galaxies probed in absorption using bright background sources such as quasars or Gamma-ray burst afterglows. Previous meetings of people working in this area were organised in Chicago (2009), Marseille (2010), Boulder (2011), Pune (2012) and Marseille (2013).

A conference in memory of Jean Heyvaerts will be held from Nov. 17 to 19, 2014 at the Institut d’Astrophysique de Paris, France. The conference aims at giving an overview of the diverse fields to which he contributed with deep and novel ideas. Discussed topics will include magnetic structures from stellar to cosmological scales, reconnection, jets and accretion, relativistic plasmas and turbulence, and cosmic-ray acceleration.

«Which astrophysical site for the r process ? The role of neutron star mergers.»
Entrée est libre. Présentations invitées :
Andreas Bauswein (MPA Garching) : Mergers and Gravitational Waves
Frédéric Daigne (IAP - UPMC) : Cosmic evolution of Europium, SNII vs NS mergers
Andy Gallagher (Observatoire de Paris-Meudon, GEPI) : Observational constraints on r process elements
Stéphane Goriely (Université Libre de Bruxelles) : r process nucleosynthesis
The series of "European Workshops on Collisionless Shocks" has been initiated at the Centre de Recherches en Physique de l’Environnement (named later Centre d’études des Environnements Terrestre et Planetaires - CETP), Issy les Moulineaux, in France, March 1991. Collisionless shocks are met and/or invoked in a large variety of domains in Plasma Physics
Cet atelier, financé par le Programme National Hautes Energies (PNHE), se propose de discuter différents aspects de ce domaine de recherche très vivant. Il rassemble à cet effet théoriciens des hautes énergies, modélisateurs, physiciens des plasmas, physiciens de l’interaction laser-plasma et experts en simulations numériques (MHD, PIC) pour confronter leurs points de vue, donner lieu à de nouvelles collaborations et développer de nouveaux outils d’analyse.

«Euclid Seminar : school for Engineers»
ESA and the Euclid Consortium are organising a set of lectures for engineers and scientists working on the Euclid mission. The aim of the "Euclid Seminar" is to strengthen the links between the EC and ESA teams set for the implementation phase, and to help bring everyone up to a common level of understanding with respect to the Euclid science, instruments and mission. The Euclid Seminar will take place at IAP, from September 10 to 14, and will be organised in pedagogical lectures given by ESA and Euclid Consortium scientists presenting the science (cosmology and legacy), specific technical aspects (measurement techniques,survey), the payload (telescope, VIS and NISP instruments) and the science ground segment.
In 1982, seminal work showed the puzzling behaviour of Lithium7 in low-metallicity, halo stars of our Galaxy. Those observations did in fact establish the paradigm of a Lithium7 abundance constant in stars spanning three orders of magnitude in metallicity. Since then, this finding has challenged our understanding of Stellar Atmospheres, Cosmological Nucleosynthesis and Stellar Formation environments, becoming known as the "Lithium Problem".
Depuis deux ans, sous l’impulsion d’une bourse Egide entre la France et la Corée du Sud, nous tentons de développer des collaborations étroites et privilégiées entre le département d’Astrophysique GEM (Galaxy Evolution Meeting) de l’Université de Yonsei (Séoul - Corée du Sud) dirigé par le Prof. Sukyoung Yi, et le CRAL (Centre de Recherche d’Astrophysique de Lyon) et l’IAP pour la partie Française. Au cours des deux dernières années, plusieurs ateliers dans lesquels ont participé des chercheurs et étudiants des deux parties ont déjà eu lieu soit en Corée du Sud soit en France.
The workshop has the ambition to gather together cosmologist and relativists active in the field of cosmological backreaction. The main goal is to give them the chance to present and to discuss their latest results in an informal setting and to have open discussions in order to discuss the status of this question and identify the problems to be overcome in the coming years.
