Facilities

• UKIRT 3.8-m Telescope (~20 nights per year)• Maidanak 1.5-m Telescope (Uzbekistan, 2 months per year, S

NU4kCAM)• 6.5m Radio Telescope on campus• Small Telescopes on campus

• AKARI (ISAS/JAXA)

14-16 January, 2009 Subaru User’s Meeting (NAOJ)

Surveys

• SNUQSO (Seoul National University Bright Quasar Survey in Optical)

Bright quasar survey in the zone of avoidance [PI: Im]

• IMS (Intermediate-wide, Medium-deep Survey in NIR) ~ 150 square degree NIR imaging survey (~23 AB mag; PI: Im)

• QSONG (AKARI Spectroscopy Study of Quasars) 2.5 – 5 micron NIR spectroscopy of z > 3.4 quasars (PI: H. M. Lee, M. Im)

14-16 January, 2009 Subaru User’s Meeting (NAOJ)

AKARI Collaboration

Software contribution(1 faculty + several junior scientists

at ISAS always)

Scientific collaboration(Large surveys,

Mission programs)

Example: North Ecliptic Pole (NEP) Survey(5.8 square degree)

: many core Japanese astronomers (mostly ISAS) + 3 key SNU astronomers (H. M. Lee, M. G. Lee, & M. Im)

Optical+NIR imaging (BRI + JH) Spectroscopic data (> 1000 redshfits)Papers (11 micron sources, etc)

SPICA Collaboration

Example 2: CLEVL (Cluster Evolution Study)

PI: H. M. Lee (SNU), low-z (M. G. Lee), mid-z (Takagi), high-z (Takagi/Watarai) + Japanese/SNU participants

14-16 January, 2009 Subaru User’s Meeting (NAOJ)

Previous + Current Subaru-related collaborations

• Small projects:

Stellar clusters (Arimoto + M. G. Lee) IC10 (Karoji, + M. G. Lee, M. Im) High-z galaxy, quasar search projects (PIs: Kashikawa, Hibon, + Im) AKARI-related (Takagi, Wada, Kodama, Hanami, etc + SNU AKARI group)

• Man Power: NAOJ postdoc (N. Hwang)

14-16 January, 2009 Subaru User’s Meeting (NAOJ)

Future Collaboration

• More small collaboration projects

• Collaboration of large-scale programs, surveys HSC? WFMOS? (AKARI) Scientific projects + Instrumentation projects SNU can possibly lead such collaborations (e.g., CEOU resources)

• Joint workshop

• Exchange of research personnel (postdocs, students)

• http://astro.snu.ac.kr

14-16 January, 2009 Subaru User’s Meeting (NAOJ)

Possible ideas

• Two of Astronomy faculties are GMT Korean science working group members (M. G. Lee, & M. Im)

Discussion on projects on route to GMT era is on-going (Subaru project?)

• CEOU is starting a survey project (8-years) and possibly instrument project

Funding available

150 square degree NIR imaging survey

14-16 January, 2009 Subaru User’s Meeting (NAOJ)

CEOU/Astronomy Projects
