Conference starts at 02:33. The Paris Institute of Astrophysics is going live! The 11th "remote" conference will take place on Tuesday, January 5, 2021 at 7:30 p.m., and will be given by François Bouchet (astrophysicist, research director at the CNRS, director of the IAP from January 1, 2021). 50 minutes of presentation, followed by your questions on the chat: • COSMOLOGY TODAY: ANSWERS ... Astrophysics is incredibly rich in extraordinary discoveries that renew our vision of the world, from the discovery of multiple exoplanets with unexpected properties, the opening of a new window on the Universe thanks to gravitational radiation, to the exploration of the confines of space and time revealed by cosmology. The Planck space mission has just delivered its latest results, largely based on the work carried out at the Paris Institute of Astrophysics. I will talk about the purpose of this mission - the detailed mapping of the fossil radiation - the results obtained by analyzing the data and comparing them with those obtained by other methods. If cosmology now has a standard model, many questions remain open and many experiments are underway to try to answer them. Is the revolution just around the corner? In any case, IAP researchers are present on all these fronts! The program of our upcoming remote conferences: http://www.iap.fr/science/conferences/
