Cosmic magnetic fields

le 23 septembre 2022, 11h à 13h, Katia Ferrière, salle Jules Verne, OMP, site Belin Magnetic fields are ubiquitous in the Universe. Most celestial bodies, from planets to stars to galaxies, appear to be magnetized. Even intergalactic space could be threaded by a magnetic field. Cosmic magnetic fields generally play an important role. They affect […]

Searching for new and rare objects in the Universe

le 30 septembre 2022, 11h à 13h, Natalie Webb, salle Jules Verne, OMP, site Belin Thanks to large surveys such as Gaia, the Sloan Digital Sky Survey (SDSS), GALEX, 2MASS, NVSS, FIRST, XMM-Newton and Chandra, we have catalogued many different stars and galaxies. We have also found some very exotic objects, especially when we observe […]

The Cosmic Microwave Background, instrumentation and data analysis

le 9 septembre 2022, 11h à 13h, Louise Mousset, salle Jules Verne, OMP Resumé: The measurement of the B-mode polarization of the Cosmic Microwave Background (CMB) is one of the major challenges of observational cosmology. The signal is expected to be of the order of a few tens of nK, prone to instrumental systematic effects and […]

A Universe of waves

le 2 septembre 2022, 11h à 13h, Arturo Lopez Ariste, salle Jules Verne, OMP Resumé: The phase of a wave can only be defined unambiguously for complex waves. This strange quantity appears at the core of all physics: from the quantification of atomic levels or of the electric charge to the source of the electromagnetic interaction […]

Astrometry & Astrophysics : an insight into the Gaia space mission

le 17 novembre 2021, 14h00 à 16h00, Philippe Tatry, salle de conférence, IRAP, site Roche Philippe TATRY (Airbus Space Systems) will present the Gaia space mission that is dedicated to compile a 3D space catalogue of more than 1 billion stars, celestial objects, … based on a huge volume of astrometry & astrophysics data collected […]

Probing the innermost region of the accretion flow in active galactic nuclei

le 8 novembre 2021, 15h45 à 17h45, Elias Kammoun, salle Coriolis, OMP Active galactic nuclei (AGN) are one of the most powerful and radiatively efficient sources in the universe. AGN are thought to be powered by accretion of gas onto a supermassive black hole (SMBH; M~10^6-10^9 solar mass). They are known to emit light through the […]
