The lab regularly hosts colloquia and workshops that focus on particular subjects
which are chosen amongst the different fields and projects of the lab.
These meetings last several days and are intended for professionals only.
This is the first of a new series of meetings (several a year) aimed at fostering scientific interaction among the vast and active community of early Universe cosmologists in the Paris area, including PhD students and postdocs. Each meeting will take place in a different institute. The format of the meeting is informal, with invited guests as well as shorter talks plus ample time for discussion.
This workshop explores the recent developments in the field of multifield inflation, with special emphasis on the role of the geometry of the field space manifold. Talks on selected topics and time for informal discussions are planned, with the aim of favouring interactions and exchange of ideas amongst participants. Topics to be covered include: non-standard attractors in curved field space; inflation with non-geodesic motion; geometrical destabilization of inflation; embeddings in high-energy physics; implications of the swampland conjectures; (p)reheating in curved field space.
Born in the aftermath of the firt wold war, the International Astronomical Union (IAU) had to cope with many crises and conflicts between nations. After the second world war, the IAU played an important role in building bridges between their astronomers. A one-day "IAU@100" celebration is held at Institut d’Astrophysique de Paris and the Observatoire de Paris, and will address in particular the creation of the IAU, the China crisis, the adherence of Germany, the USA-USSR Moon race, the little known, but acute conflict between the IAU and the United Nations about lunar nomenclature after the Moon landings, and the fruitful cooperation with UNESCO.
This goal of this meeting is to gather the Euclid consortium members involved in the scientific activities related to the strong gravitational lensing effects. In the meeting, several organizational aspects are addressed, especially those related to the buildup of the lens finding pipelines. Some of the most relevant science goals benefiting from the Euclid statistical power of strong lensing events are also tackled.
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. The goal of this workshop is to bring together researchers working on theoretical aspects, statistical methods and observational cosmology, in order to discuss: the synergies between different cosmological observables in answering the fundamental questions in the field of astrophysics and cosmology; the synergies between different cosmological missions which are required to achieve maximum gains from the data sets of the upcoming missions; the theoretical aspects which we will learn from the synergetic studies, the readiness of numerical simulations, and the required statistical methods for the analysis of data from these different probes.
