- FOCAS IFUの開発とその性能
- Abstract
-
我々が開発を進めてきたすばる望遠鏡の可視光撮像分光装置FOCASに組み込む面分光ユニット（Integral Field Unit;
IFU）が2018年2月にファーストライトを迎え、今年6月から共同利用に用いられるようになった。この開発においては先端技術センターの多大な協力を得られたおかげで、複雑な形状ながらも高い精度が必要なキーコンポーネントを完成させることできた。本講演ではこの面分光ユニットの開発を振り返り、試験観測で評価された装置の性能について報告する。最後にTMTの可視光撮像分光装置WFOS用の面分光ユニットへの発展についても述べる。 - 連絡先

- Pathway to numerical simulations of stripped-envelope supernovae
- Abstract
- Stripped-envelope (Type IIb and Ib/c) supernovae form a special group among core-collapse SNe, because their progenitors lost the H and He layers during the pre-supernova evolution. Because of this mass-loss the debate on the surrounding envelope of these objects has not been settled yet. Moreover, the analytic models also deepen this issue, because there is a discrepancy in the gained ejecta masses from early- and late-time light curve fits. Due to this complex physical nature, theoretical models are essential to understand better the physics of this kind of exploding stars. Here I present a possible method for modelling the progenitor and the circumstellar environment of these stripped-envelope SNe, which could help to solve the mass discrepancy problem via semi-analytic and hydrodynamic simulations.

- “WFIRST: Dark Energy and Exoplanets”
- Abstract
- The top recommendation for a large space mission in the US 2010 Decadal Survey was the Wide Field Infrared Survey Telescope (WFIRST). Similarities in hardware requirements between proposed dark energy, exoplanet microlensing, and near infrared surveyor missions allowed for a single mission that would accomplish all three goals. The gift of an existing 2.4 meter telescope to NASA by another US government agency allowed for the addition of a coronagraph that will take images and spectra of nearby exoplanets; this instrument will be a technological stepping stone to imaging other Earths in the 2030s. I will give an overview of WFIRST’s proposed instrumentation, science goals, and implementation plan. I will delve into the details of a number of scientific and technical efforts that are paving the way for this ambitious and exciting mission.

- HabEx: The Habitable Exoplanet Observatory
- Abstract
- The Habitable Exoplanet Observatory (HabEx) is one of four flagship mission concepts studied by NASA in preparation for the 2020 US Astrophysics Decadal Survey. HabEx is designed to be the next-generation space-based great observatory with ultraviolet, visible, and near-infrared imaging and spectroscopy capabilities, and ~50% of the primary 5-year mission dedicated to community involvement through a competed and funded Guest Observer (GO) program. HabEx will also seek out nearby worlds to explore their habitability and will map nearby planetary systems to understand their diversity. The HabEx concept is scientifically compelling, technologically and financially feasible for launch in the 2030’s, and also enables a balanced NASA mission portfolio in the next decade. This talk will introduce the HabEx mission concept and present some of the cutting-edge science that will be enabled by a large aperture, highly capable, ultra-stable space-borne telescope.
