\nI will present the recent results of the Planck satellite mission, by
\nintroducing first of what consists the CMB science. I will then reveal what we
\nlearned from Planck about our Universe: his age, his history, his content. I
\nwill then focus on what has been learned thanks to the polarization
\ninformation provided by Planck, especially concerning the importance of the
\nGalactic foregrounds when searching for gravitational wave’s signatures into
\nthe CMB maps.\n<\/p>\n
\nWe have combined the Planck-HFI and IRAS maps to perform an all-sky detection
\nof the cold submillimetre Galactic sources over the whole sky, to build the
\nThe Planck Catalogue of Galactic Cold Clumps, counting 13188 sources. I will
\ndescribe how we proceed to build this catalogue using an original
\nmulti-frequency detection method, and how we characterized this population of
\nobjects using new distance estimates for one third of them. I will finally
\ndiscuss the results provided by the Herschel Galactic Cold Core follow-up Key
\nProgramme of about 350 PGCC sources, yieldings important clues about the early
\nphases of the star-formation.<\/p>\n","protected":false},"featured_media":0,"template":"","tags":[],"seminar_category":[53],"acf":{"s_now_accepting":true,"s_date_order":"2015-04-16 13:30:00","s_date_end":null,"s_date_text":"","s_text":"Ludovic Montier","s_place":"KMI Science Symposia (ES635)","s_place_other":"","s_categoryother":"C-KMI Joint Seminar","s_poster":"","s_poster2":"","s_slide":""},"yoast_head":"\n
