2015 国立天文台特別公開講座/総研大入試ガイダンス(関東会場)

2015年5月23日(土)、国立天文台三鷹キャンパスにおいて「国立天文台における天文学研究の最前線」をテーマに特別講演会および総研大入試ガイダンスが行われました。今年は学部の1年生から社会人の方まで総勢約40名の方々が参加されました。

特別講演会では、青木和光准教授(TMT推進室)、立松健一教授(チリ観測所)、竝木則行教授(RISE月惑星探査検討室)、浜名崇助教(理論研究部)らによって観測、理論における天文学の最前線についての講演が行われました。
特に、竝木則行教授による「惑星探査:生命のゆりかごを探して」ではアストロバイオロジーについて地球進化の話も踏まえて生命存在の可能性の話があり、他の発表者も巻き込むような質問も出てきていました。その他の発表についても参加者のなかから多くの鋭い質問が出てきていました。

Star Forming Molecular Gas in Early Stage Mergers
[Abstract]
While the simulations have predicted a number of intriguing aspects of the gas response during the early stages of a galaxy collision, only a handful of observational tests exist in literature so far. We performed observation of early stages galaxies with Nobeyama45m CO(1-0) and ASTE10m CO(3-2). An extensive survey of molecular gas along the complete merger sequence will finally allow us a detailed comparison with the predictions from numerical simulations.

Rapid dust production in Hα-8μm-selected galaxies at z=2 / Addressing the Evolution of Super-massive Blackholes with Hyper Suprime-Cam Survey

Rapid dust production in Hα-8μm-selected galaxies at z=2
[Abstract]
I present results on the dust obscuration of star-burst galaxies at z=2 selected by MIPS/Spitzer and MOIRCS/Subaru, towards on-going programs with ALMA. Thanks to our past narrow-band imaging survey (Mahalo-Subaru), we have a large sample of Hα-selected star-forming galaxies. By combining them with MIPS 24um data, we probed ~50 dusty galaxies with IR luminosities above 5E11 Lsun. Since those also have spatially-resolved rest-UV image taken by Hubble Space Telescope, we can study morphological dependence of dust properties (IRX=IR/UV). Our preliminary results show that for a given UV slope, “UV-saturated” galaxies have more heavily-obscured UV structures, which directly indicates that dust covering fraction increase rapidly than intrinsic UV luminosity as suggested by Reddy et al. 2010. Moreover, such highly-obscured galaxies tend to have high equivalent widths of Hα emission, which is also good agreement with dust properties of massive galaxies at low redshift (Koyama et al. 2015).
