Abstract Our understanding of current cosmological observations and the formation of the great structures of the Universe (galaxies and beyond) is based in part, in the standard cosmological model, on the existence of an effective fluid of cold dark …

Abstract There are several cosmological constraints for finding candidates, coming from galaxies, clusters, but also constraints from quantum physics, fermions or bosons. Particle physics points to a wide variety of candidates   : weakly interacting WIMPS …

Exceptionally, the seminar will take place on a Monday. Sophie Bava: "Migrations and religious transformations between sub-Saharan Africa, Mediterranean Africa and Europe" Lucine Endelstein: "Jewish worlds, minorities and mobilities. An urban …

Abstract We consider a stochastic control problem with unknowns, inspired by neuroscience. In this model, a neuron is characterized by its membrane potential and emits discharges randomly, with a rate that depends on its potential and an unknown …

Abstract Fregean senses are associated with a subject-centred rather than ecological view of reality. On this traditional view, intentional content is fixed from inside the mind, via subjects' grasp of what they are thinking of, rather than by features of …

Abstract During the instability of giant planets, the trans-Neptunian disk is completely dispersed. Some of the objects are then thrown towards the interior of the Solar System, causing intense cometary bombardment of the terrestrial planets. The …

One-hour lecture , followed by the seminar. Abstract The planetary instability described by the Nice model proposes a Neptune dynamic that differs in part from the gradual outward migration previously used to explain the structure of the Kuiper belt (see …

Abstract The publication in 1499 of the Hypnerotomachia Poliphili , attributed to Francesco Colonna, by the publisher Aldo Manuce in Venice, marked the beginning of a learned and original mode of expression whose few surviving productions span a little …

Abstract Based on decades of scientific development in a highly collaborative environment, numerical climate models are essential tools for understanding and anticipating climate impacts and risks. Initially developed in a research context for large-scale …

Abstract Although climate should not be reduced to temperature, it is the simplest parameter to describe and quantify. Global warming over the last two  hundred years, and particularly since 1970, is undeniable, but some see it as the result of urban …

Abstract The earliest funerary statuettes were included in the funeral trousseaux of the First Intermediate Period and the Middle Kingdom in the form of single specimens. During the New Kingdom, the number of statuettes per deceased grew considerably, …
