12. 暗物质的天体物理与宇宙学研究 Astrophysical and Cosmological Determinations of Dark Matter THCA Charling Tao and Shan Huan Yuan • Analyze existing CFHT data • Prepare for Large suveys. • LSST, EUCLID, KDUST • Collaboraton with • + IHEP • +NAOC • +PKU • +…

13. My mission: Develop THCA • Understanding the Dark Universe: astroparticle, Cosmology and gravity physics • CMB analysis, SNIa: TNT, SNfactory, Dome A • (DM): JinPing collaboration on low background environment • Attract more people (students, postdocs, faculty, visitors) to develop existing and more fields of research • Internal Tsinghua - Stronger involvement in teaching - Develop collaborations with Computer, Engineering departments • Develop collaboration with NAOC, PMO and IHEP • International collaborations • Access to existing data • Future Chinese projects, eg Antarctica • Visiting scientists  Need a regrouped space to improve research environment • Need lab space for experimental/observational R&D developments

14. SNFactory II/PTF Still need more and better measured nearby SNIa for  calibration  understanding of SNIa subclasses  need more SNIa detected before maximum for better maximum determination • New Collaboration : US (Berkeley, Yale) + France+ Germany + Tsinghua using the now well running SNIFS spectrograph in UH 2.2m • MOU with Yale telescope in Chile and Palomar Transient Factory (PTF) group for SN detection Use of Chinese telescopes for trigger? under study (Xuyu， Xinlong，Lijiang ）  THE spectrophotometric SNIa reference!

15. South Pole Dome A Kunlun Telescope will answer fundamental questions about the structure of the Universe. Wang Lifan Advantage: great seeing! Expect: 0.3 arc sec, eg space

16. Towards a large South Pole Dome A Kunlun Dark Universe Survey Telescope (KDUST) • Multiprobe measurements (SNIa, Weak Lensing, BAO, Clusters) for cosmology and ancillary science • First stage 2011-2013: 3 x 75 cms telescopes (AST3) - Already designed, one AST3 under construction, - Installation in Dome A starting in fall 2011,  THCA contributes to one AST3 and take responsibility for SN search (need computing capability) 2.5 m KPATH (Kunlun Pathfinder): 2012-2016 - Discussions with Australian, US, French • Larger (> 4m) KDUST: Timescale too early to define!
