J-TMT instrument review meeting
http://jelt.mtk.nao.ac.jp/tmtinst/

ATC (Advanced Technology Center)ATC has opt./mechanics/electronics facilities and ~20
engineers.
Important infrastructure for developing Subaru instruments.
They are currently working on ALMA.
TMT project was approved to be the most promising major
project that ATC should pursue in the next decade.
Good news for future developments of IRIS and the 2ndgen. instruments

Synergy with Subaru
Subaru will turn to a “survey telescope” in the next decade.
The most unique capability: Prime Focus (30’ FOV),
Suprime-Cam (Wide field camera) & FMOS (Wide field NIR
fiber spectrograph)
Subaru has explored w/ wide FOV:The highest-z galaxies
LSS and clustering of high-z galaxies
Global structure of clusters of galaxies
Outer halo structure of nearby galaxies…
New (upgraded) instrument
PF: Hyper Suprime-Cam (HSC) & PFS
IR: HiCIAO+ExAO, WF AO, IR high-res. spectrographSubaru/HSC survey
Subaru/Hyper Suprime-Cam(1.5deg FOV) will be able tooffer some of interesting targets that TMT will follow-up:– high-z LAEs/LBGs– high-z QSOs
– faint BzKs/DRGs– high-z SNe– stars in outer halo of nearby galaxies– …
Find w/Subaru and examine w/TMTFMOS/PFS for bright targets and TMT for faint targets
Similar synergy w/LSST, and complementary to JWSTSubaru/SEEDS project
