Satellite observation of clouds : a bird's-eye view on all time and space scales
Seminar

Abstract From the first photographs taken from V2 rockets in 1948 to recent observations by the EarthCare mission, satellite observation of clouds has undergone spectacular development in terms of spectral, spatial and temporal sampling. These …

Abstract Clouds have a major influence on climate balance. On the one hand, they reflect part of the sun's radiation back into space ; on the other, they contribute to the greenhouse effect. These two processes have broad but opposing impacts on the …

Abstract We have completed the demonstration of Mc Shane's formulas, generalized by Mirzakhani. These are remarkable geometric identities, valid on any hyperbolic surface with an edge, relating the lengths of the edges of the "hyperbolic pants" contained …

Abstract The study of various examples of " substitution cults ", particularly in the Osirian domain, leads us to question the rules of ritual practices and their constants in ancient Egypt. This phenomenological approach provides a clearer picture of …

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 …

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 …

All the fundamental interactions (electromagnetism, weak and strong nuclear forces, gravitation) are described by " gauge theories ", i.e. theories that are invariant to transformations depending on arbitrary functions of time, implying redundancy in …

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 …
