The Planck Catalogue of Galactic Cold Clumps
Title:
The Planck Catalogue of Galactic Cold Clumps
Speaker:
Dr. Ludovic Montier (CNRS, IRAP, Toulouse, France)
Abstract: We have combined the Planck-HFI and IRAS maps to perform an all-sky detection of the cold submillimetre Galactic sources over the whole sky, to build the The Planck Catalogue of Galactic Cold Clumps, counting 13188 sources. I will describe how we proceed to build this catalogue using an original multi-frequency detection method, and how we characterized this population of objects using new distance estimates for one third of them. I will finally discuss the results provided by the Herschel Galactic Cold Core follow-up Key Programme of about 350 PGCC sources, yieldings important clues about the early phases of the star-formation.

「宇宙科学談話会(第12回)」 日時: 2015年4月1日(水) 16:30-17:30 場所: 宇宙研 A棟2階 大会議場 講師: 福島登志夫 (国立天文台) 題目: ハンバーガー、バナナ、クレープ、そしてバウムクーヘンの重力場 概要: 世の中には奇妙な形をした天体が飛び交っている。ある准惑星はハンバーガーみ たいだし、別の小惑星はバナナ(それとも鰹節?)の形をしている。また、土星 の輪のようにクレープやバウムクーヘンと例えるほうが適切なものもある。この ような天体の近くを周航したり着陸しようとすると、それらの重力場を計算した り解析する必要に迫られる。しかしながら、お決まりのレシピ(=球面調和展開) は、(ブリュラン散乱で有名な、あの)ブリュリランの呪いにより、必ずしも使 えるとは限らない。ここでは、著者の悪戦苦闘の数々を、やや物語風にお伝えす る。詳しい(真面目な?)情報をお望みの方は、以下のWEBサイトをご参照く ださい。 https://www.researchgate.net/profile/Toshio_Fukushima Space Science Colloquium Date: 16:30-17:30, 1 April (Wed), 2015 Place: Conference room (Main building 2F) Speaker: Toshio Fukushima (National Astronomical Observatory Japan) Title: Gravitational Field of Apple, Banana, and Crepe (ABC) Abstract: Funny objects are flying across the universe. Some planets recall apples, some asteroids are banana-shaped, and Saturnian rings look like crepe. If you (or a space mission) want to get close to, move around, and/or land on them, you need to estimate, measure, and/or analyze their gravitational fields. Nevertheless, the routine recipe named the spherical harmonic expansion does not always work due to the curse of Brillouin, who is famous for Brillouin scattering and stands for B of the WKB approximation. This talk rephrases the author's hard days to tackle this fundamental problem as a sort of fairy tale.
