[Title]
13C isotopic fractionation of HC3N in star forming regions
[Abstract]
I will talk about observations with the Nobeyama 45-m telescope during this observational season. We investigate 13C isotopic fractionation of HC3N and discuss its main formation mechanisms in L1527 and G28.28-0.36.

Chemical Composition in a Merging Galaxy NGC3256 ~ALMA new results~ / Physical Conditions of Molecular Gas in Merging Starburst Galaxy NGC 1614

Chemical Composition in a Merging Galaxy NGC3256 ~ALMA new results~
[Abstract]
NGC3256 is late stage merging galaxy and SB/AGN activity is considered to strongly impact the chemical and physical properties of ISM. Chemical properties as traced in molecular gas composition contain significant information that will tell us the current state and duration of the SB/AGN activities, and how that is affected by the ongoing tidal interaction. The spectrum of our previous LMT line survey seems to be like SB galaxies not AGN-host galaxies, however it reflects mean value of double nuclei. High resolution and sensitivity imaging of numerous molecules with ALMA is strong tool to create accurate picture of NGC3256. We introduce the newest results of ALMA cycle3 observation.

[Title]
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs)
[Abstract]
I will present recent updates of high-redshift (z>6) quasar search project using Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) survey, with which we have succeeded in identifying 9 z>6 quasars from the initial data release. Also, I will show the result of another faint quasar search at z~6 using deep Subaru/Suprime-Cam images.

2016 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)

 2016年5月21日(土)、国立天文台三鷹キャンパスにおいて、特別公開講演および総研大入試ガイダンスが行われました。本年も学部1年生の方から社会人の方まで、総勢約51名の方々にご来場いただきました。
 今年度は『国立天文台における天文学研究の最前線』テーマに、小山佑世助教、井上剛志助教、伊王野大介准教授、麻生洋一准教授の4名の先生方から、それぞれの分野の視点に立った興味深いご講演をいただきました。質問の時間には、小山先生の問いかけから、参加者の方々の中でも興味が様々であることがわかりました。観測をしたい方、理論研究に興味がある方、装置開発に携わりたい方、そしてそれらを並行したいという方もいらっしゃいました。
