LAPTh, an overviewLAPTh is a mixed research unit (UMR 5108) of the CNRS (within the Institute of Physics, INP) and the Université de Savoie. It is located in Annecy-le-Vieux, 5km from the centre of Annecy and about 40km from CERN and Geneva. The activities of LAPTh are centred around three main areas of research:
NewsA course on cosmology by Wessel ValkenburgStarting Monday 20 January Wessel Valkenburg (Lorentz Institute, Leiden Univ., NL) will give a series of 5 lectures on cosmology. The lectures require no prior knowledge of the subject and is addressed to both theorists and experimentalists, physics PhD students and researchers alike. The 5 lectures Introduction to Cosmology cover The (6) videos of the lectures can be found on the LAPTh Youtube Channel Habemus LogoA new logo is born !LAPTh has now a new logo! Putting 5 letters in a square was no easy job. Among a hundred of designs and a lot of discussions in the LAPTh patio, restaurant, sometimes heated but always jovial, this was the final choice. The logo comes now in a couple of versions.
New Planck results, another one bites the dustAfter four years of operation of the Planck satellite of the European Space Agency (ESA), the Planck Collaboration has build up an exquisitely precise map of the sky in both temperature and now of polarisation. These maps furnish a detailed picture of how the universe evolved. Among the numerous results provided by the Planck satellite over the last year, there is an assessment of the polarised dust emission at intermediate and high Galactic latitudes (http://arxiv.org/abs/1409.5738). This is a crucial foreground in the searches for primordial B-mode polarisation patterns, possibly imprinted in the Cosmic Microwave Background by gravitational waves of inflationary origin, also known as tensor modes. Thanks to this measurement, older estimates of this contribution have been revisited and, in a joint effort by the BICEP2/Keck Array and Planck Data collaborations (http://arxiv.org/abs/1502.00612), no statistically significant evidence for tensor modes has been found in a reanalysis of the BICEP 2 observations, which in 2014 had been interpreted as a possible primordial B-mode detection (http://arxiv.org/abs/1403.3985), an interpretation that made big waves in the media then... undeservedly. We will need to wait and be more careful about gravity waves. Group Theory Lectures 2015
