• Parameter estimation in linear sparse regression

    Salle Lyot - IRAP Belin 14 avenue Edouard Belin, Toulouse, FR

    Pierre Barbault (IRAP) What do the radial velocity of a star, a spectral mixture and the electromagnetic field produced by the brain have in common?  In all three cases, one might describe the data as a linear combination of a small number of elementary signals, sometimes called ‘atoms’ (sinusoids, spectra, peaks, dipoles, etc.). Introduced in the […]

  • Cross-scale plasma coupling – the secrets of cosmic transients and space weather

    Salle Lyot - IRAP Belin 14 avenue Edouard Belin, Toulouse, FR

    Rungployphan (Om) Kieokaew (IRAP) Cosmic plasmas drive dynamical processes throughout the universe, from magnetic field generation to explosive energy conversion. Magnetized plasmas in the solar system are the most accessible environments for in-situ measurements. Unlike theoretical or numerical simulation approaches, where assumptions about plasma behavior must be made a priori (i.e., on large, fluid-like, or […]
