Supermassive Black Hole Mass Estimation Using Molecular Gas Kinematics Observed with Millimeter/Submillimeter Interferometor
[Abstract]
Ubiquitely present at the centres of galaxies, supermassive black holes (SMBHs) are key to understand galaxy evolution. However, the SMBH mass-central velocity dispersion relation, which is driving most theoretical efforts, is based on a relatively small number of measurements and only a handful of methods.
Our recent work has shown that it is straightforward to dynamically estimate the mass of SMBHs, by simply probing the near-Keplerian rotation of molecular disks around them at high angular resolution. In the ALMA era, this can yield hundreds of measurements in galaxies of all morphological types.
In the talk, I will show the SMBH mass measurement in NGC 1097 by using ALMA Cycle 0 observation, and also in NGC 3665 by using CARMA observation.

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。
