Subaru’s Synergy with TMT

• Direct imaging of exoplanets and exploration of life outside of the solar system

• Uncover the first born star/galaxy• Understand dark matter and dark energy

Subaru Telescope(8.2ｍ)

Discovery of numerous galaxies approximately 13 billion light-years away

Successful direct imaging of exoplanets

Science goals of TMT

TMT will attempt to solve the mysteries of universe uncovered by Subaru Telescope

Exploration of the accelerating universe based on wide field galaxy survey using HSC/PFS

Hawaiiʼs Public Opinion: We Continue to Support TMT

12/28/2015 – 1/9/2016 (post-HSC decision)Honolulu Star-Advertiser public opinion pollPerformed by Ward Research Inc., *619 polled“Do you support or oppose moving ahead with the construction of the TMT on Mauna Kea?”

Yes 67%No 27%

(The poll is 39% Yes and 59% No when the result is limited to native Hawaiians)

5/15/2016 (prior to the pre-hearing)Honolulu Star-Advertiser readers poll*1341 polled“What do you think about the restartof the TMT permitting process?”

Positive 88%（1182）Negative 8%（ 107）

TMT Backup PlanSite Other than Hawaii

Construction in Hawaii is still the first choice, but a course of action must be considered in case construction in Hawaii is deemed not possible. Each partner country is in the process of compiling opinions on this issue.

Schedule proposed by TMT International Observatory:Oct 26~27, 2016 Board meeting: Narrow down alternate sites (cf. La Palma @Spain, SPM @Mexico, MacKenna & Honar @Chile) for the backup plan

The conditions and timing for the decision on whether or not to construct in Hawaii (switch to BackupPlan) is under discussion

ß For Japan, Hawaii is very essential, it is not easy to change the plan.TMT-J SAC holds several meetings to understand the current status of TMT project and to make decision on the direction regarding the following to prepare for the possibility of construction not taking place in Hawaii (Aug 2 Kyoto, Sep 1 Sendai, Sep 6 Hilo, Sep 9 Tokyo, Sep 12 Hiroshima).Discussions continue at TMT SAC meetings (last one on Sep 26th)
